摘要
研究了液固两相区压缩变形对 Si Cw/6 0 6 1Al复合材料组织和性能的影响。结果表明 ,压缩变形温度对变形后复合材料中晶须长径比、取向 ,复合材料组织的致密性、均匀性和界面结合状态均有不同程度的影响。复合材料组织的变化又影响到复合材料的性能。复合材料高温大变形后性能的变化是评价复合材料高温塑性成形加工工艺的最重要指标。通过分析复合材料的组织和性能 。
Effect of compression deformation at temperatures in the solid liquid two phase region on the microstructure and properties of SiC w/6061Al composites was investigated in the present study.It was found that the aspect ratio and orientation of whisker,densification and uniformity of composites,and interfacial bonding were affected more or less by compression deformation temperature.The properties of composites were affected by the changes of composite microstructure.The changes of composite properties after large deformation which took place at high temperatures were the most important index for evaluating high temperature plastic forming.The best compression deformation parameter was determined by analyzing the microstructure and the properties of composites.
