Abstract：

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.
