Abstract:A multi-step thermo-mechanical treatment(MSTMT) was developed to refine the microstructure of Ti-33Al-3Cr-0.5Mo(%)alloy.It was found that fine full lamellar structure can be obtained by appropriate procesing of MSTMT.Superior comprehensive mechanical properties can result from the full lamellar structure with homogeneous fine grain.
Key words: intermetallic compounds; mechanical properties; microstructure
