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

摘要

PROBLEM TO BE SOLVED: To provide a Ti-Al-based alloy ingot having ductility at room temperature, in which the Ti-Al-based ingot has a lamellar structure in which αphases and γ phases are arranged sequentially and regularly, and a thickness ratio γ/αof the γ phase to the αphase is equal to or more than 2.SOLUTION: 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 αphases and γ phases are arranged sequentially and regularly, and the γ phase has a thickness of 100 nm to 200 nm, and the αphase has a thickness of 100 nm or less.
