摘要
利用ＮｉＴｉ合金薄屑吸氢后球磨制备了直径为６ｕｍ以上的各种尺寸的颗粒，含氢ＮｉＴｉ颗粒经脱氢处理后具有可逆相变，随颗粒位尺寸减小，相交点稍有降低。
The preparation of particles more than 6um in diameter by ball-milling theNi-50.2at% Ti alloy hydrogenated was investigated. The dehydrogenated NitiH_X particleshave reversible phase transformation. The phase transformation temperature of particlesdecreases slightly with the decrease of particle size.
