Hybrid Manufacturing: Influence of Directed Energy Deposition Parameters on Microstructure and Layer Adhesion of Stainless Steel 316L
Authors: Hamilton Jakob D. , Sorondo Samantha , Greeley Andrew , Kahn Bruce E. , Cyr Patricia , Cormier Denis , Rivero Iris V. 
Published: September 2021

Abstract
In-envelope hybrid manufacturing systems comprised of directed energy deposition (DED) and machining provide flexibility for the fabrication of complex geometries with minimal setup changes. However, for these manufacturing set ups, the effects of deposition parameters such as laser power and scanning speed on the quality of the build remain relatively unexplored. An important aspect for developing components with reliable mechanical properties is a thorough understanding of DED thermodynamics during fabrication. Therefore, DED thermodynamics were defined based on the strengthening properties derived from the thermal gradient (G) and solidification rate (R) of the melt pool. Other factors influencing DED thermodynamics include substrate geometry and surface finish which are expected to affect cooling rates and adhesion, respectively. In this work, stainless steel 316L specimens were fabricated varying laser power intensity, scanning speed, and deposition substrate. The effect of these parameters on the microstructure of the sample components were analyzed. Microstructural evolution at various points within and between layers was studied and correlated to localized hardness. An increase in mechanical properties for fine, equiaxed grains demonstrates the Hall-Petch principle for strengthening of components.

Authors: Armuth Andrew , Grider Nicholas 
Published: September 2021

Abstract
The current Automotive Industry Action Group (AIAG) CQI-9 audit process has limited effectiveness to proactively detect heat treatment quality risks in Tier-1 and Tier-2 supply bases. A cross-functional engineering organization developed an improved supplier audit form using CQI-9, National Aerospace and Defense Contractors Accreditation Program (NADCAP), International Automotive Task Force (IATF), and specific internal company standards to distinguish and quantify production issues that may have been undiscovered with the existing CQI-9 approach. Representatives from engineering, commercial, and manufacturing crafted a more complete approach to supply chain quality. This new audit format (Beyond CQI-9) has demonstrated the ability to quantify heat treatment concerns, reduce future engineering resource costs, and develop new and existing heat treatment suppliers to meet world class quality levels.

Reducing Furnace Operating Costs: IGBT/MFDC Technology Saves on Energy
Authors: Pridmore David H. , Rutkowski Stanley F. 
Published: September 2021

Abstract
This paper describes a furnace retrofit involving the replacement of a variable reactance transformer (VRT) with an IGBT-controlled mid-frequency direct current (MFDC) transformer. The two transformers are similar in size and all other variables remained essentially equivalent. A typical heating cycle was initiated with a ramp rate of 10°F/min to a soak temperature of approximately 1900°F. Cross-sectional data was taken during the ramp phase and soak phase. Based on power measurements and adjusting for differences in thermal loads, the retrofit achieved a 40% reduction in kilowatt consumption, a 14% reduction in peak current draw, and an improvement in power factor throughout the cycle.

How to Put Predictive Maintenance to use on the Internet of Things
Authors: Goldsteinas Aymeric 
Published: September 2021

Abstract
This paper presents four case studies documenting the time and money that heat treaters have saved with the help of predictive maintenance tools. In one case, a heat treater avoided potential catastrophic melting of a heating element and several hangers when predictive maintenance software guided the operator to a broken ceramic in a specific heating zone. In another case, a commercial heat treater was alerted to a low kW reading, indicating a heater failure on a diffusion pump, which would have led to the contamination of a vacuum furnace if not addressed in a timely manner. Situations involving a failing motor on a quench tank and the degradation of furnace insulation are also discussed. Cost comparisons, with and without predictive maintenance, are included in three of the four studies.
