Abstract

For promoting the commercial application of third-generation advanced high-strength steels in the automotive industry, the enhancement of the mechanical properties and formability of medium-Mn steel is becoming a research hotspot. Use of self-developed hot-forming steel, the microstructure evolution on mechanical properties affected by composition and hot forming parameters of Fe-0.1C-7Mn-3Al-1.5Si medium-Mn steel was investigated in this work: analyze microstructure transformation of medium-Mn steel under hot forming process through SEM, XRD and etc.; and take the tensile strength, elongation and work hardening rate as evaluation index to study the influence on the properties of test steel such as heating process, partitioning temperature. Microstructural transformation and mechanical properties relationship are comprehensively analyzed in the test results, providing theoretical basis for optimizing the thermoforming process parameters. Achieve the goal of meeting excellent mechanical properties requirements and weight reduction of automotive components.
