1- A polycrystalline aluminum alloy contains a dispersion of hard particles of diameter 10-8 m and average center-to-center spacing of 6 x 10-8 m measured in the slip planes. Estimate their contribution to the tensile yield strength, y, of the alloy. G = 26 GN/m and b = 0.286 nm. 1- A polycrystalline aluminum alloy contains a dispersion of hard particles of diameter 10-8 m and average center-to-center spacing of 6 x 10-8 m measured in the slip planes.
