Influence of Thermal Exposure at Different Temperatures on Room Temperature Tensile Ductility of Cast TiAl Alloy

Influence of Thermal Exposure at Different Temperatures on Room Temperature Tensile Ductility of Cast TiAl Alloy

The effect of thermal exposure at 600-750℃ for 300h in atmosphere on room temperature tensile ductility of cast Ti-47.5Al-2.5V-1.0Cr-0.2Zr(atom fraction/%) was investigated.The results indicate that no surface layer on the specimen surface is observed after exposure at 600℃,but tensile ductility at...
