steel research international, Volume 96, Issue 2, February 2025.A low‐carbon (0.23 wt%) carbide‐free bainitic steel is successfully developed with a total alloying addition of 4.9 wt%, which is relatively lower than alloying additions reported in similar category of steels. The present findings indicate that the currently designed low‐alloy steel composition is amenable to generation of nearly carbide‐free bainitic

The Effect of Cryogenic Treatment on W360 and E38K Hot Work Tool Steels
steel research international, Volume 95, Issue 9, September 2024.The cryogenic treatment facilitates the transformation of retained austenite to martensite to an undetectable limit, with about 3 times higher amount of the carbide precipitation for both steel types. Both steel types exhibit almost similar impact energy values at room temperature, but E38K steel has 2 times higher energy at 350 °C.

Determining Factors of Grain Size in Bainite Structure of Fe–2Mn–C Alloys
steel research international, Volume 95, Issue 8, August 2024.The crystallographic variants and effective grain sizes of bainitic ferrite in Fe–2Mn–C alloys with various carbon contents are determined by local orientation measurements. Decrease in transformation temperature is beneficial for grain refinement of bainite structure although effects of carbon content are different between low‐carbon and high‐carbon ...
