title: EH36 steel for shipbuilding - Charpy impact test reslut in vary tempetatures

description: The basic method of ductility designation of structural steels is the Charpy impact test. The test consists of a single strike of the specimen using a Charpy pendulum. Its result is the value of work necessary to break a specimen at a test temperature. Despite its many advantages, such as its short implementation time and low costs, it has its disadvantages, in particular:
• strong influence of notch geometry on the test result, which means that impact strength cannot be considered as an unambiguous material property,
• milled notches are not repeatable because the cutter wears,
• regardless of the thickness of the material being tested, samples of the same size are used.
Due to these disadvantages, for very responsible ship and ocean engineering constructions, such as: continuous longitudinal coamings of the largest container ships, or supporting components of drilling platforms, tests are carried out basing on fracture mechanics. For shipbuilding industry, CTOD (Crack Tip Opening Displacement) is, the most often, desired value. The test CTOD is performed by slowly bending the specimen with record of the slit opening. Before performing the test, it is necessary to know the material properties (from a tensile test). The final stage of the test is the measurement of the initial fatigue fracture geometry.
Dataset contains results of Charpy impact test in  20 ° C, 0 ° C, -20 ° C, -40 ° C and - 60 ° C

title: The structure of lead-silicate glasses containing nanocrystallites of iron oxides

description: The structure of iron-doped glasses and glass-ceramics were studied. Samples has the composition of  (50 − 0.5x)SiO2–(50 − 0.5x)PbO–xFe2O3, where x = 2, 5, 10, 15, 20 and 25 (in mol%). All samples were prepared by the conventional melt quenching technique; the melting was conducted in air at 1623 K in alumina crucibles. The melts were poured on a brass plate preheated to 573 K and formed into button-shaped samples. Afterwards pellets were annealed at 673K, cooled with the furnace. The presence of crystalline phases was examined by the X-ray diffraction method with the use of a Philips X'Pert Pro MPD system with CuKα radiation.

title: Determination of the ratio resistors in the input circuits of the NTC10k thermistor calibration system

description: The presented data set is part of the research aimed at determining the actual characteristics of each thermistor in a package of twenty NTC10k type sensors.
The measurement system is shown in Fig. 1. A measurement system based on NI PXIe-1082Q (National Instruments Chassis), equipped with NI PXIe-8135 (Embedded Controller), NI PXIe-6341 (DAQ card) and NI SCB-68A (68-pin connector block), was used for the acquisition of measurement data. Eleven input channels of the DAQ card were used in the measurements. Channel 0 (ch_0) was used to measure the supply voltage. Sensors numbered 1 to 20 were tested in two parts, ten sensors per set. They were connected to the inputs of channels 1-10 (ch_1-ch_10) of the DAQ card.
The conditioning unit for individual sensors is shown in Fig.2. These circuits are performed on connector block SCB-68A as the voltage dividers. For the set of ten thermistors, the supply voltage is measured in channel 0 (ch_0) of the DAQ card, and individual thermistors are connected to channels 1-10 (ch_i).  Fig. 1. The measurement setup  
To make further calculations of the thermistor resistance and other parameters, we need to know the resistance values R in each measurement channel (from ch_1 to ch_10). The measurement results included in the data set 5001.zip, composed of ten files 5001kx.lvm (where: x is from 1 to 10) allows determining the R-value in each channel. They are obtained in the circuit, as shown in Figure 2, wherein the place of the thermistor in each of the measurement channels, a standard resistor with a resistance of 5001 Ohm was used.                                                                                                               Fig. 2.

title: Mechanical properties of VL E27 steel for shipbuilding – fracture documentation (test in 0°C)

description: One of the basic divisions of steels used for ship hulls and ocean engineering structures is the division into: normal strength steels, high strength steels and extra high strength steels. The belonging to the group is determined by the mechanical properties of the steel, such as: yield point, ultimate strength and plastic elongation after fracture. The steels in each group are divided into categories, differing in the minimum required breaking energy at a specific temperature, determined in the Charpy test. For applications on a more responsible hull structure or offshore structure, additional steel tests may be required - determination of fracture toughness. In the shipbuilding industry, it is most often CTOD (Crack Tip Opening Displacement) test.
The published data concern testing the fracture toughness of VL E27 steel for shipbuilding, with  nominal thickness of 35 mm. It is the first steel from the group of high strength steels. It is characterized by an early low carbon content, as for hull steels, which is one of the reasons for its high ductility. The average carbon content in the tested material was 0.16%. The scope of the tests carried out so far is: tensile test at + 20 ° C, 0 ° C, -20 ° C, impact test at temperatures: 20 ° C, 0 ° C, -20 ° C, -40 ° C, - 60 ° C and a fracture toughness test at temperatures of 20 ° C, 0 ° C, -20 ° C.
The dataset contains the photographic documentation of fracture, measurement of fatigue precrack length and measurement of final crack extension.

title: Change of reaction quotients for SOFC fueled by biogas mixture at 750 C

description: The dataset contains the Change of reaction quotients for SOFC fueled by biogas mixture at 750 C (60:40 CH4:CO2). The outlet concentration of the gases from SOFC were measured using novel FTIR-based unit. 
Measurement procedure:
"Several approaches concerning equilibrium calculations for methane reforming were already mentioned in other publications [45], [46], [47], [48]. In order to determine the behaviour of each from series of mentioned reactions, a time-dependent thermodynamic analysis was performed using reaction quotients (Qr) [45], [46], [49], which represent a ratio between an actual non-equilibrium constant and equilibrium constant of a specific reaction. Qr value aids in figuring out the momentary direction in which reactions are likely to proceed. Mathematically Qr is calculated from Eq. (24) as a ratio of actual overall partial pressures pi of species "i" raised to the power of stoichiometric coefficient xi (positive for products and negative for reactants) and equilibrium constant Kp,r of discussed reaction. Each of the mentioned reactions was taken into account separately for Qr value estimation in order to simplify the calculation method while providing sufficient enough data for further analysis of equilibrium shifting. All theoretical equilibrium constants Kp were taken from the HSC ChemistryTM software. [...] Quotient indicates if the mentioned reaction goes to the right (for Qr &lt; 1) or to the left (for Qr &gt; 1). When Qr = 1 reaction has reached an equilibrium point. It is commonly approved that Qr∼10−3 stands for the situation when mostly reactants are present in reaction area, while Qr∼103 when nearly all substances are products and finally if 10−3&lt;Qr &lt; 103 then significant amounts of both reactants and products are visible " (10.1016/j.ijhydene.2019.03.243)
