steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

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.

Bainitic stabilization of austenite in low alloy steels
, 1992 Stabilization of retained austenite via bainitic transformation was studied in a triple-phase, ferrite/bainite/austenite steel 0.26C1.52Si-1.2Mn. Volume fraction and stability of retained austenite are varied by isothermal transformation time at 752F ...

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

Transformation of residual austenite under thermomechanical variations
, 1999 The austenite to martensite transformation seems to have an influence on the resistance to micro-pitting. Then, the residual austenite transformation was studied for different thermal and thermomechanical conditions.
