【摘要】 本文研究了SiCw/6061Al复合材料和基体合金在液-固两相区及固相区的压缩变形行为。得到了复合材料试样压缩变形高度减少极限量和压缩应力随变形温度,应变速率的变化规律。通过测试不同工艺参数压缩变形后材料的性能,获得了SiCw/6061Al复合材料超塑变形的最佳工艺参数。更多还原

【Abstract】 Compressive deformation at temperatures below and above the solidus of the matrix alloy of SiCw/6061Al composites and 6061A1 was investigated in the present study. Relationships between the critical reduction and the deformation temperature, critical reduction and the deformation strain rate were obtained. Compressive flow stress dependence of deformation temperature and strain rate were found. Through analysis of the properties of composite post-compression, the optimum Compressive parameters were determined.更多还原
