摘要
对快速凝固Ｃｕ０．６Ｃｒ０．１５Ｚｒ０．０５Ｍｇ合金伴随时效析出的再结晶过程进行了观察和研究。发现该合金在形变后的时效过程中，析出相非常细小、弥散，阻碍了再结晶的进行，出现了原位再结晶与不连续再结晶同时发生的现象。在再结晶的形核和长大过程中，析出相在晶界前沿快速粗化或重新溶解，并在再结晶区域中重新析出，导致更加弥散的析出相分布。
The recrystallization process during aging for a rapidly solidified CuCrZrMg alloy was investigated. It was found that the discontinuous recrystallization process has been partially retarded by the ultrafine and dispersed precipitation during aging after deformation. Thus, a phenominon of simultaneous in situ and discontinuous recrystallizations has been observed in the rapidly solidified CuCrZrMg alloy. On the formation and growth fo recrystallization, the precipitated phases are coarsened and dissolved in the front of grain boundaries following a reprecipitation in the recrystallization area, which results in the much more dispersed precipitation of the phases.
