采用X射线应力分析技术测定SiC颗粒体积分数为20%的SiCp/6061Al复合材料由外加载荷作用而产生的基体铝合金相的实际外载应力,据此计算增强相的实际外载应力.结果表明,基体铝合金相的实际外载应力为平均外载应力的75.9%,而增强相的实际外载应力为平均外载应力的196.6%两相弹性模量的差异是造成这种现象的主要原因
The actual loading stresses of the matrix in a SiCp / 6061A1 composite caused by applied loads were measured by means of x-ray stress analysis method, and those of the reinforcement in the composite were calculated based on the measured results. The exper
