Authors: Gu Jianfeng , Xu Jun , Simencio Otero Rosa L. , Viscaino Jônatas M. , Canale Lauralice C.F. , Totten George E. 
Published: September 2021

Abstract
In this investigation, the authors use a Tensi probe to obtain cooling curves for canola and palm oils and determine their heat transfer coefficient profiles. For comparison, the cooling curve of an accelerated petroleum oil quenchant is also presented. Canola oil exhibited minimal evidence of film boiling, while palm oil showed a pronounced film boiling behavior. This behavior suggests the presence of unrefined volatile by-products or subsequent degradation. The petroleum quenchant exhibited wetting front movement along the Tensi probe not observed with the vegetable oils.

Authors: Arimoto Kyozo 
Published: September 2021

Abstract
A variety of test systems have been developed to determine the cooling characteristics of quenchants. Although current test standards specify cylindrical probes for measuring quenchant temperatures and cooling rates, this review concerns the development, implementation, and potential of test systems that use ball probes instead. It assesses the strengths and limitations of different types of ball probes and describes prototype test systems that leverage ball probe capabilities while compensating for inherent weaknesses.

Published: September 2021

Abstract
Plain carbon steel cylinders were heat treated and quenched in order to study the effects of heat treating on residual stresses and microstructure. Residual stress measurements were obtained via X-ray diffraction using the sin2Ψ method and microstructure was characterized based on the associated peak widths. Measurements were made both at the surface and through depth following electropolishing. Triaxial stress gradients were observed in all test samples with concomitant varying microstructural characteristics. The method used to measure residual stresses in this study is typical and recommended for general practice.

Published: September 2021

Abstract
Forging processes include various steps to attain favorable material properties such as heat treatment, rapid quench, cold work stress relieving, and artificial aging. These steps, however, also contribute to bulk residual stress. Excessive bulk residual stresses cause a wide of problems, including part distortion during machining and in use, reduced crack initiation life, increased crack growth rates, and an overall reduction in part life. This paper summarizes recent work aimed at measurement-based assessment of bulk residual stresses in cold-compressed aluminum die forgings. The results show that forging process induced residual stress is a repeatable phenomenon with RMS repeatability less than 5% of yield.
Heat Treating of EV Transmissions
Authors: Beauchesne Dennis 
Published: September 2021

Abstract
As consumers embrace Electric Vehicle (EV) technology, the automotive industry is moving quickly into replacing internal combustion engines (ICE) and traditional transmissions. The change to electrically driven vehicles offers new challenges to the gear manufacturing world, and most importantly new specifications to heat treat these gears - specifically quieter gear sets and higher torque ratings. Today’s EVs have a much lower tolerance for noise from the gear set to power the vehicle; therefore, this continues the need for even quieter and stronger gears. This technical presentation will illustrate the heat treat and distortion specifications for these new gears, along with answering the “why” of selecting low pressure vacuum carburizing (LPC) for new programs around the world.
Hydrogen Generation Facilitates Sintering Atmospheres
Authors: Wolff David 
Published: September 2021

Abstract
For annealing, brazing or sintering, furnace atmospheres help ensure that metals thermal processors obtain the results they need. Hydrogen-containing atmospheres are used to protect surfaces from oxidation, and to ensure satisfactory thermal processing results. Hydrogen-containing atmospheres make thermal processing more forgiving because the hydrogen improves heat conduction and actively cleans heated surfaces – reducing oxides and destroying surface impurities. For powder based fabrication such as P/M, MIM or binder-jet metal AM, the use of a hydrogen-containing thermal processing atmosphere ensures the highest possible density of the sintered parts without necessitating the use of post-processing techniques. Users of pure hydrogen or hydrogen-containing gas blend atmospheres often struggle with hydrogen supply options. Hydrogen storage may create compliance problems due to its flammability and high energy content. Hydrogen generation enables hydrogen use without hydrogen storage issues. Deployment of hydrogen generation can ease the addition of thermal processing atmospheres to new and existing processing facilities.

Abstract
Heat treaters are adopting more and more Industry 4.0 techniques and solution packages to improve production processes and product quality. Proper specification, measurement, and control of heat-treating atmospheres are always critical to achieving the desired metallurgical and microstructural results. The combination of atmosphere measurements and other furnace operating parameters (e.g., furnace temperature and pressure) can provide a better view of the whole production. Thermodynamic calculations and field experiences can be integrated into the smart solution to provide process engineers more capabilities to manage and optimize production. In this article, our recent research and development work on smart solutions for the heat-treating industry will be presented and discussed.
New Generation Press Hardening Steels with Tensile Strength of 1.7-2.0 GPa and Enhanced Bendability
Authors: Tedesco Sarah , Shi Ming , Coryell Jason , Lu Qi , Wang Jianfeng 
Published: September 2021

Abstract
Press hardening steel (PHS) applications predominately use 22MnB5 AlSi coated in the automotive industry. This material has a limited supply chain. Increasing the tensile strength and bendability of the PHS material will enable light-weighting while maintaining crash protection. In this paper, a novel PHS is introduced, and properties are compared to 22MnB5. The new Coating Free PHS (CFPHS) steel, 25MnCr, has increased carbon, with chromium and silicon additions for oxidation resistance. Its ultimate tensile strength (UTS) of 1.7 GPa with bending angle above 55° at 1.4 mm thickness improves upon the 22MnB5 grade. This steel is not pre-coated, is oxidation resistant at high temperature, thus eliminating the need for AlSi or shot blasting post processing to maintain surface quality. Microstructural mechanisms used to enhance bendability and energy absorption are discussed for the novel steel. Performance evaluations such as: weldability, component level crush and intrusion testing and e-coat adhesion, are conducted on samples from industrial coils.
Relationship Between Deep Case Carburizing and Residual Stress in Rolling Contact Service
Authors: Meyer Jason , Habean Stefan , Londrico Dan , Sims Justin 
Published: September 2021

Abstract
The notion that compressive residual stresses can extend the service life of components subject to rolling contact fatigue is well documented. However, the exact nature of the relationship between effective case depth and the residual stress state is not well understood for components with case depths greater than 0.050 in. (1.27 mm). It is expected that compressive residual stresses gradually transition to tensile stresses as case depth increases beyond a threshold value. This study will measure the residual stress state of components with different case depths before and after simulated service in order to determine where the compressive to tensile transition occurs. It will also investigate the role of retained austenite and the effect of strain-induced transformation caused by rolling contact. Residual stress and retained austenite measurements will be conducted using X-ray diffraction.
Fr. Georges Florovsky’s Theology of History as the Mainstream of Neo-Patristics
Authors: Рупова Розалия Моисеевна 
Published: September 2021

В статье дана характеристика концепции неопатристического синтеза, претерпевшей существенные изменения за период, прошедший с момента её провозглашения протоиереем Георгием Флоровским в 1936 г. Имея вначале довольно обобщённый характер, она уточнялась, интегрируя в свой состав результаты осуществлённых за прошедшие годы междисциплинарных исследований, приобретая со временем характер методологически выдержанного дискурса. В этом интегральном дискурсе, включающем богословие истории, экклезиологию, антропологию, богословие культуры - богословие истории имеет характер стержневой концепции, определяющей архитектонику всего здания неопатристического синтеза. В статье дан обзор работ Флоровского, посвящённых теме христианского понимания истории, за весь период его публикационной активности. Это позволяет отследить эволюцию и различные грани богословия истории прот. Георгия.
The article characterizes the concept of neo-patristic synthesis, which suffered substantial changes since it was declared by Fr. Georges Florovsky in 1936. Being initially rather abstract and generic, it gradually gained in precision and detail, incorporating the results of subsequent multidisciplinary studies, and acquired the features of methodologically rigorous discourse. In this integrated discourse, which also includes ecclesiology, anthropology, theology of culture, theology of history plays the role of the core concept, determining the architectonics of the whole building of neo-patristic synthesis. The author consecutively reviews all Florovsky’s works dedicated to the Christian understanding of history. This allows to trace the evolution and different shades of Fr. Georges’ theology of history.
Biblical Apologetics: Metahistory and Causal Retrospection
Authors: Мумриков Олег 
Published: September 2021

Православная христианская традиция рассматривает «естественное зло» - присутствие в природе естественных катаклизмов, страдания и смерти - как следствие первородного греха Адама и Евы. Однако научная картина мира объективно убеждает нас в обратном: «естественное зло» - неотъемлемая характеристика вселенной с момента её возникновения. С богословско-апологетической точки зрения данное противоречие может быть разрешено при взгляде на мировую историю в свете двух событий - грехопадения и искупления как метаисторических, влияющих как на будущее, так и прошлое посредством Божественного предвидения. Автор приводит обоснование возможности данного подхода.
The Orthodox Christian tradition considers «natural evil» - the presence in nature of natural cataclysms, suffering and death as a consequence of the original sin of Adam and Eve. However, the scientific picture of the world objectively convinces us in the opposite - «natural evil» is an integral characteristic of the universe since its inception. With the theological and apologetic point of view this contradiction can be resolved when you look at the history of the world in the light of two events: fall of man and Redemption as a superor meta-historical, which influenced the future and the past by Divine foresight. The author provides a rationale for the possibility of this approach.
Learning of the Second Coming of Christ in 1 Epistle of the St. Apostle Paul to the Thessalonians (1 Thess. 5, 1-11): An Experience of Theologicaland Exegetical Commentary

Published: September 2021

В статье рассматривается отрывок из первого послания апостола Павла к Фессалоникийцам (1 Фес. 5, 1-11), темой которого является учение о последних временах, о Втором пришествии Христа и о времени его наступления. Эсхатологическое учение является основным в богословии этого послания. Данное учение следует рассматривать в контексте нравственных наставлений апостола Павла верующим фессалоникийцам, в которых образ «сынов света» является основным для обозначения христиан.
The article examines a fragment from the First Epistle of the Apostle Paul to the Thessalonians (1 Thess. 5, 1-11), the theme of which is the doctrine of the last times, the Second Coming of Christ and the time of His coming. The eschatological teaching is fundamental in the theology of this Epistle. This teaching should be considered in the context of the moral instructions of the Apostle Paul to the faithful Thessalonians, in which the image of the «sons of the light» is the main one for designating Christians.
