【Abstract】 The effect of rare earth and Al-Ti-B on the grain size and mechanical properties of 6063 aluminum alloy was studied.The results showed that the grain was refined remarkably after the addition of rare earth and Al-Ti-B.The tensile strength and elongation of 6063 aluminum alloy were both increased obviously.更多还原
