【Abstract】 A JCXA-733 electron microprobe was used to investigate solid solution strengthening mechanismand nonequilibrium solidification behavior in W-Ni-Cu heavy alloy. The characteristics of fractographic microstruc-ture was related to the mechanical properties and density. The fracture mechanism of heavy alloy was clarified. The ways to improve properties of heavy alloy were proposed.更多还原
