Ti-Al-BASED ALLOY INGOT HAVING DUCTILITY AT ROOM TEMPERATURE

摘要

There is provided a Ti—Al-based alloy ingot having ductility at room temperature, in which the Ti—Al-based ingot has a lamellar structure in which α₂ phases and γ phases are arranged sequentially and regularly, and a thickness ratio γ/α₂ of the γ phase to the α₂ phase is equal to or more than 2. There is also provided a Ti—Al-based alloy ingot having ductility at room temperature, in which the Ti—Al-based alloy ingot has a lamellar structure in which α₂ phases and γ phases are arranged sequentially and regularly, the γ phase has a thickness of 100 nm to 200 nm, and the α₂ phase has a thickness of 100 nm or less.
