摘要：
The mechanical properties and deformation behavior of Ti-5Al-2. 5ZrELI alloy compared with Ti-5Al-2.5 SnELI at 4.2 K, 20 K and 293 K were investigated. The results show that the new titanium alloy Ti-5Al-2. 5ZrELI has more consistent properties because of its uniform microstructure and less segregation, it has good elongation and ductility. The fracture surfaces are covered with elongated dimples at cryogenic temperatures. The deformation mode at 293 K, 20 K and 4.2 K are twinning and slipping.
