研究了过时效 Al-2 质量% Cu 合金在蠕变过程中析出物的粗化行为，并特别参考了蠕变应变的影响。夹具和量规零件之间平均析出物尺寸的比较表明，蠕变应变增强了蠕变过程中析出物的生长。这一事实强烈表明位错与溶质气氛的运动促进了溶质通过位错核的传输。 (C) 2004 Elsevier B.V. 保留所有权利。
The coarsening behavior of precipitates was investigated of an over-aged Al-2 mass% Cu alloy during creep with a special reference to the effect of creep strain. Comparison of the mean precipitate size between grip and gauge parts showed that the creep strain enhanced the growth of precipitates during creep. This fact suggests strongly that the motion of dislocations with solute atmosphere promotes the transport of solutes via dislocation core. (C) 2004 Elsevier B.V. All rights reserved.
