Research on Mechanical Stability of Austenite in TRIP Steels

XIONG Zi-liu,CAI Qing-wu,JIANG Hai-tao,TANG Di(Engineering Research Institute,University of Science And Technology Beijing,Beijing 100083,China)  
Mechanical stability of austenite in TRIP steels was studied using techniques such as tension test,XRD,EBSD,SEM,TEM.The results showed that austenite converted fast at early tension,and slow at upper tension.With the different carbon content,the increasing rate of convention percent of austenite was different in the same tension stage.Austenite which dimension exceed 1μm and allocated on grain boundary or phase boundary almost completely transformed to martensite at early tension,while austenite which dimension less than 1μm would transform to martensite at upper tension,which could release the stress concentration on grain or phase boundary and contributed a lot to TRIP effect.Austenite which allocated in ferrite was of good mechanical stability and not liable to transform to martensite in the whole tension test,and some big dimension austenite would transform to M-A island.
