Effect of chromium addition on microstructure, tensile properties and creep resistance of as-cast Ti-48Al alloy

The effect of Cr on the microstructure, tensile properties and creep resistance of as-cast Ti–48Al–xCr (x = 0, 2, 4 at.%) alloys were studied. The dependence of the tensile properties and creep resistance of as-cast TiAl on the solid solution strengthening and formation of b phase due to addition of Cr was investigated.
