15%SiC颗粒增强铝基复合材料等温变形的显微组织研究

Study on Microstructure of 15%SiC_P/Al Composites in Isothermal Deformation

研究了锻造温度为440℃和480℃、变形速度为1mm/min和10mm/min的条件下,15%SiC铝基复合材料等温变形前后的组织变化。结果表明,SiC颗粒在等温变形前后形状尺寸基本不变,在基体中分布均匀;在440,480℃变形温度下,变形量、变形火次、变形速度等参数对材料的组织有一定的影响。

The microstructure of 15%SiCp/Al composites in isothermal deformation was studied under the condition that the deforming temperature is 440, 480℃, the deforming rate is 1,10mm/min. The results show that the size of SiC panicles and microstructure of 15%SiCp/Al composites change a little after isothermal deformation.
