Paper Title:
Effect of RE on the Mechanical Properties of 7075 Al Alloy
  Abstract

We set 7075 Al alloy as the object of study,expecting to optimize alloy formula and find the optimal dosage of rare earth in order to improve its mechanical properties by adding different percentages of the rare earth elements,the results show that:When the rare earth content reaches 0.3%,with the two-stage aging treatment,7075 Al alloy′s tensile strength comes to 420.76MPa and elongation comes to 16.80%.Compared with the exclusing rare earth group,7075 Al alloys′ tensile strength increased about 8.4% and elongation only falls by 2.3%, so the mechanical performance is the best.
