Effect of chromium addition on microstructure and creep strength of as-cast Ti-48Al alloy

Effect of chromium addition on microstructure and creep strength of as-cast Ti-48Al alloy

The microstructure and creep behaviour of as-cast gamma titanium aluminide based alloys with nominal composition of Ti-48Al, Ti-48Al-2Cr and Ti-48Al-4Cr (at.%) were investigated. Constant load tensile creep tests were performed at temperature and stress of 800 °C and 150 MPa, respectively. Creep cha...
