steel research international, EarlyView.A new austempering approach following intercritical austenitizing is explored to improve the mechanical behavior of API 5CT steel. By tailoring ferrite–bainite microstructures, the process achieves a balance of strength and ductility without the need for post‐quench tempering. The results highlight a cost‐effective alternative to conventional quenching

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

Thermomechanical Processing, Microstructure, and Mechanical Properties of Medium‐Mn Steel
steel research international, EarlyView.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.

steel research international, EarlyView.A cross‐scale modeling strategy is developed to predict failure and formability of DP780 steel by linking microstructural features with macroscopic behavior. Crystal plasticity and macroscopic damage models are integrated and validated through nanoindentation, in situ bending, and finite element simulations.

steel research international, EarlyView.The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

Comparative Characteristics of Martensite and Bainite in Cu-Based SMAs
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2014 The present work reports the evolution of micro-structure and shape memory behavior in a Cu-15 Zn-6 Al (mass. %) shape memory alloy (SMA), as a function of the applied hot working procedure and of the performed heat treatments.
