摘 要: 研究了氢原子对Ti-Fe系机械合金化的影响.应用XRD,DSC;TEM等方法测试了Ti—Fe系和Ti-Fe-TiH2系的机械合金化反应过程和产物结构的特征.研究结果表明,氢原子在机械合金化过程中诱导非晶TiFe相的形成由于氢原子的影响,非晶TiFe(H)相的结构弛豫温度和晶化温度低于机械合金化得到的非晶TiFe相相应的温度. The solid reactions and structures of Ti+Fe and Ti+Fe+TiH2 during mechanical alloying were studied by using XRD, DSC etc. The results show that hydrogen can induce amorphization of TiFe in MA. The characteristic temperatures of amorphous TiFe(H) phase, such as structure relaxation and crystallization temperatures, are lower than that of the amorphousTiFe phase synthesized by mechanical alloying.
