Study on Compressive Performance of SiC_P/Cu Gradient Composite
SiCP/Cu gradient composite was fabricated by powder metallurgy.The compressive performance of the composite was studied.The results show that the specific density of the composite can be increased and the gradient boundary layers can be eliminated by second compressing power metallurgy technique.When the pressure reaches 630 MPa,the composite generates macroscopical shear crack,which is 45° in vertical direction.After compression test,the average density of the composite increases from 95.8% to 97%.
