Abstract

The purpose of this paper is to look at how annealing time affects the microstructure and mechanical characteristics of lightweight medium manganese steel. OM, XRD, SEM, and other characterization methods were used to examine and test the microstructure. The findings revealed that the test steels’ microstructures were all composed of martensite, α-ferrite, δ-ferrite, and retained austenite. The retained austenite content of the test steel appears to increase after a certain time of annealing treatment. The TRIP effect created by stretching increases the mechanical properties of the test steel.
