摘要：

Intergranular　corrosion　and　stress　corrosion　cracking　resistance　of　Al-Zn-Mg-Cu　alloy　with　trace　Er　addition　were　examined　by　means　of　stress　corrosion　cracking　and　intergranular　corrosion　testing　from　GB-T7998-2005　and　HB5254-83,　and　microstructure　of　the　alloy　was　observed　by　OM　(optical　microscope)　and　SEM　(scanning　electron　microscope).　The　results　indicate　that　trace　Er　addition　can　greatly　improve　intergranular　corrosion　and　stress　corrosion　cracking　resistance　of　the　alloy,　however,　with　more　than　0.4%　Er　addition,　stress　corrosion　cracking　resistance　will　be　descended.
