摘要

In this work, the bainite transformation during isothermality of aluminium bearing TRIP steel was studied by dilatometric experiment on a push-rod Formastor-F Ⅱ high-speed dilatometer with radio frequency induction heating. The aluminium bearing TRIP steel consisted of the microstructure of austenite, ferrite and bainite in the form of laths which produced by intercritical annealing and isothermal transformation followed by rapid cooling. The effect of intercritical annealing temperature and isothermal transformation temperature were studied by dilatometric experiment and JEOL JXA-8530F Electron Probe Microscopic Analyzer (EPMA).
