摘要：

Effect　of　homogenization　annealing　on　microstructure　and　properties　of　5E61　alloy　was　studied.　Microhardness　and　conductivity　of　the　alloy　were　tested,　and　microstructure　was　studied　by　means　of　scanning　electron　microscopy　and　transmission　electron　microscopy.　The　results　show　that　the　microhardness　and　conductivity　of　the　5E61　alloy　are　significantly　improved　during　homogenization　annealing,　and　the　precipitates　in　the　alloy　become　finer　and　better　dispersed　after　two-stage　homogenization.　After　homogenization　annealing　at　320　℃　for　20　h　and　then　at　450　℃　for　20　h,　the　dendrite　structure　of　the　5E61　alloy　is　eliminated,　the　residual　second　phase　at　grain　boundary　is　the　least　and　the　elements　in　the　microstructure　are　uniformly　distributed,　indicating　that　it　is　the　best　homogenization　annealing　process　©　2018,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
