常温で延性を有するチタン−アルミニウム系合金インゴット

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.
