Description
この特徴によれば、従来においては困難とされていたTiおよびCrの2元系合金やV元素、Mo元素、Al元素、W元素、希土類元素などの含有量が少ない組成を有する合金においても、BCC型相を主相とする水素吸蔵合金を得ることが可能となる。
このようにすれば、熱処理工程の時間が1分未満だと、充分なBCC型構造相の形成が得られず、1時間を超えると熱処理コストが上昇するだけでなく、異相が析出して水素吸蔵特性が劣化する副作用も現れることから、処理コストの上昇を抑えつつ、良好なBCC型構造相の形成を得ることができる。
このようにすれば、これら合金はコストと単位重量当たりの水素吸蔵量に優れた高い実用性を有する水素吸蔵合金を安定的にBCC型構造を主相とした合金とすることができる。
このようにすれば、これら合金はコストと単位重量当たりの水素吸蔵量に優れた高い実用性を有する水素吸蔵合金を安定的にBCC型構造を主相とした合金とすることができる。
