研究了轧制方式、轧制温度等对SiC颗粒增强铝基复合材料显微组织和力学性能的影响。轧制温度为410℃,沿平行于挤压方向进行交叉轧制可以制备出高质量、高性能的薄板。轧制态7075/SiCp复合材料薄板的力学性能为:sσ=542.51 MPa,bσ=666.09 MPa,δ=4.91%。轧制变形对挤压过程中形成的SiC颗粒条带状不均匀分布也具有改善的作用:轧制过程中,SiC颗粒破碎,尺寸明显变小,形貌呈钝化趋势,随着轧制变形量的增加,SiC颗粒分布趋于均匀。

The effects of rolling process on the microstructure and mechanical properties of the extruded spray co-deposited 7075/SiCp composite were investigated.The extruded thick sheet exhibits excellent formability along the extrusion direction.Cross rolling process can enhance the formability and mechanical properties of the 7075/SiCp sheet.Furthermore,the optimal properties of the sheet are as follows:σs=542.51 MPa,σb=666.09 MPa,and δ=4.91%.As the results of experiment,the rolling process leads to the refinement of SiC particles and the distribution state also.
