【Abstract】 The properties and microstructure of Pt-Ir-Ru solid solution alloys were studied.The results showed the additives of Ru and Ir have important influence on the properties,including mechanical properties,specific resistance and grain size,of Pt-Ir and Pt-Ru alloys.The alloys studied have high specific resistance,it is attributed to the effect of factors such as electronic scattering of the d-shell of Pt,Ir and Ru,atomic radius,structure of electron and solute concentration.更多还原
