| 摘 要： | 研究了ＭＧＨ７５４合金在二次再结晶过程中的组织和结构变化。结果表明，合金大热挤压状态具有细小的等轴晶组织，织构微弱，有利于进行殂变加工；二次再结晶后，组织为粗大的柱状晶，且出现强烈的织构；随着退火时间延长，「１１０」〈００１》和「１００」〈００１〉织构含量明显增加，而「１１０」〈１１１〉，「１１０」〈１１３〉和「１１２」〈１１１〉等织构的含量减少，合金棒材的纵向主要为〈００１〉取向。

| Abstract: | Microstructure and texture changes during secondary recrystallization of MGH754 alloy were studied. The results show that the as-extruded alloy has a fine equiaxed grain structure and weak texture. After secondary recrystallization annealing, coarse elon-gated grain structure parallel to the extrution dircction and strong texture components existed. The content of { 110} <001 > and { 100} <001> texture components increased, while {110} <111>, {110} <112> and { 112} <111> texture components decreased with the in-creasing of annealing time. The longitudinal direction of MGH754 bar is mainly <001> orientation. |
