主　　题：TRIP590 steel Retained austenite Electron backscattered diffraction Indexing rate Step size 

摘      要：The retained austenite content in TRIP590 steel was first measured by X-ray diffraction(XRD)***,the effect of different test parameters(indexing rate,step size,field number,etc.)on the measured results of retained austenite content in TRIP590 steel by electron backscattered diffraction(EBSD)method was *** comparing the measured results between XRD and EBSD method,the optimal test parameters for the analysis of retained austenite content using EBSD were ***,the total content of retained austenite and the retained austenite contents with different aspect ratios in TRIP590 steel were analyzed,*** results showed that the test parameters have a great influence on the measured results of retained austenite content in TRIP590 *** order to improve the test accuracy,high indexing rates,small step sizes and more field number are necessary for the analysis of retained austenite content in TRIP590 steel by EBSD method.
