摘要：

Martensite phase transformation and microstructure features in DP, TRIP and TWIP steels are discussed. For the obtaining of better properties, details in controlling the production of DP and TRIP steels are described based on the understanding of the stability of microstructures. Substitution of P for Al and/or Si in TRIP steel is evaluated from the aspects of thermodynamic and kinetic estimation. The minimum fast cooling rate and optimal over-aging temperature and time has been calculated for TRIP steel. Stack fault and its effect on phase transformation in high Mn steel are evaluated in the relationship with composition, strain, and heat treatment.
