近年来具有大贮氢容量材料的开发日益受到重视 ,吸氢容量可达 3% (质量 )以上的Ｔｉ3Ａｌ便是其中之一。但是Ｔｉ3ＡｌＨｘ 过分稳定 ,也就是说为其实用化的放氢温度太高。因此 ,降低这类合金的放氢温度就显得非常重要 ,近年来许多研究者研究了一些替代元素对于Ｔｉ75-ｘＡｌ2 In recent years, the development of materials with large hydrogen storage capacity has been paid more and more attention. One of them, Ti3Al, whose hydrogen absorption capacity is up to 3% (mass) is one of them. However, Ti3AlHx is too stable, that is to say, the de-hydrogenation temperature for practical use is too high. Therefore, it is very important to reduce the dehydrogenation temperature of these alloys. In recent years, many researchers have studied some alternative elements for Ti75-xAl2
