Thermomechanical Processing, Microstructure, and Mechanical Properties of Medium‐Mn Steel
steel research international, Volume 96, Issue 12, Page 252-260, December 2025.The microstructure evolution and mechanical properties of a medium‐Mn steel are investigated after thermomechanical processing and isothermal holding at various temperatures. A fine multiphase structure of bainite, fresh or tempered martensite, and retained austenite are obtained.

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with

Effect of Austempering and Martempering on the Properties of AISI 52100 Steel
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 The mechanical properties of steel decide its applicability for a particular condition. Heat treatment processes are commonly used to enhance the required properties of steel. The present work aims at experimentally investigating the effect of austempering and martempering on AISI 52100 steel. Different tests like microstructure analysis, hardness test,

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.
