Stability of retained austenite and work hardening behavior in ultra-fine medium carbon bainitic steel

open access: yesJournal of Materials Research and Technology, 2023
The effect of retained austenite stability on plastic deformation was investigated by stepwise tensile test of medium carbon steel material at two different bainite isothermal temperatures below or above the martensite start (Ms) point.

Effect of Composition on Strain-Induced Martensite Transformation of FeMnNiC Alloys Fabricated by Powder Metallurgy [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
We investigated the austenite stability and mechanical properties in FeMnNiC alloy fabricated by spark plasma sintering. The addition of Mn, Ni, and C, which are known austenite stabilizing elements, increases its stability to a stable phase existing ...
