Abstract

In order to obtain the rare earth aluminum alloy with desirable mechanical properties

the effects of different melting parameters on the mechanical properties of rare earth aluminum alloy were analyzed by orthogonal testing.The experiment results show that with La of 0.3%and pouring temperature of 660℃as well as modification at 660℃for 160min

tensile strength

elongation and hardness of the alloy reach 215.6MPa

4.7%

100.8HB

respectively.
