Since ceramic particles have both high melting point and high Young's modulus, aluminum matrix composites made from the introduced nanoceramic phase as a reinforcing phase have excellent room temperature and high-temperature properties. In addition, they have the characteristics of high dimensional stabi...
𝑣v: Poisson’s ratio of materials; 𝐸E: the elasticity modulus of materials; 𝜃0θ0: the diffraction angle without stress. The calculation was made by taking 2θ as the ordinate and sin2ψ as the abscissa, the slope obtained from this figure is the residual stress on the surface ...
