Metals, 2020 Two groups of martensitic alloys were examined for changes induced by deep cryogenic treatment (DCT). The first group was a range of binary and ternary compositions with 0.6 wt % carbon, and the second group was a commercial AISI D2 tool steel.

steel research international, EarlyView.On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Structural Phase Transformation of Rail Steel in Compression
Metals, 2022 The analysis of structure and defective substructure of rail steel in uniaxial compression to a degree of 50% is carried out. It is revealed that cold hardening has a multi-stage character and is accompanied by fragmentations of pearlite grains which is ...

An Investigation on Divorced Eutectoid Growth of Cementite in Eutectoid Steel [PDF]
Archives of Metallurgy and Materials, 2020 Divorced eutectoid growth of cementite in AISI 1080 steel is investigated as a function of cooling rate for incomplete austenitization-based heat treatment.

steel research international, EarlyView.The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels
steel research international, EarlyView.The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Justification of the Changes in Work Hardening Exponent Based on Micro-Mechanisms of Deformation in a Plain Carbon Steel [PDF]
Archives of Metallurgy and MaterialsAlthough several studies have been conducted on the evaluation of work hardening behavior of dual-phase steels with the Hollomon equation, few studies have investigated the factors affecting the number of work hardening stages and the changes of work ...

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models
steel research international, EarlyView.A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...
