Abstract : Aluminum alloy Al 1Mg 0. 6Si 0. 3Cr mechanical components with reinforced bar were added with various contents of allo-ying elements of indium and cerium, and the tensile and impact properties of components were tested and analyzed. The results show that the additional elements of indium and oerium can improve the tensile and impact properties of aluminum alloy mechanical components with
reinforced bar. The optimized contents of indiun
and cerium is 0. 5wt% and 0. 4ut% respectively. Comparing with the component without
indium, the tensile strength, yield strength,
elongatior
after fraction and impact absorptior
0.5wt% increase by 15%,25%，28%
and 41%
ectively.
Comparing with the
energy of the component with indium of
ponent without cerium, the tensile strength,
energy of the: component with cerium of 0. 4wt% increase by 17% , 18% ,
yield strength, elongation after fraction and impact absorption
30% and 22% , respectively. Comparing with the component without indium and cerium, the tensile strength, yield strength, elongation af-ter fraxtion and impact absorption energy of the component with indium of 0. 5wt% and cerium of 0. 4wt% increase by 35% , 47% , 67% and 73% , respectively-
