TiAl alloys have low density, high modulus of elasticity, better overall performance index than traditional
high-temperature alloys,and higher toughness than ordinary ceramic materials,
showing remarkable development prospects in aerospace materials,
becoming one of the representatives of a new generation of high-temperature materials,
as the material of choice for high-pressure compressors and low-pressure turbine blades of advanced
military aircraft engines with high thrust-to-weight ratio.
