Mechanical properties and deformation behavior of sprayed-deposited SiCp/7090Al composites rolling sheet were investigated by uniaxial tensile testing on WDW-E200 tensile tester at ambient temperature and 300⁴50 ℃ with stain rate of 0.1s-1. Meanwhile,microstructure,mechanical properties and fractographies of the composites at different tensile temperatures were also observed. The results show that tensile flow stress in the composites sheet is decreased with increasing in deformation temperature. In addition,interface of Al/SiC is weakened and particle breakage is reduced with tensile temperature increase,while the elongation of the composites is increased from 3.0% to 85.07%.
