摘要

摘要: 内氧化方法虽然可获得细小氧化物颗粒, 但是所得氧化物在复合材料中的分布很不均匀, 且材料致密度较低。本文研究了Al₂O_{3/Cu 复合材料的塑性变形行为, 变形材料在退火过程中的再结晶规律以及塑性变形对氧化铝弥散强化复合材料组织及性能的影响。实验证明, 该材料具有很高的加工硬化系数, 弥散氧化物能够明显提高复合材料的再结晶温度, 提高材料的高温强度。}

Abstract: Dispersive particles can be obtained with internal oxidation, but the distribution of the particles in the matrix is not uniform and the material is not dense. This article deals with the plastic deformation of Al₂O_{3/Cu composites, and the recrystallization of the deformed composites. The experiments and analyses show that the material has a high work hardening coefficient, the dispersoid can obviously improve the recrystallization temperature of the composites, and thus the mechanical properties of the composites are increased greatly.}
