摘要	The effects of recrystallization and environment (vacuum versus air) on tensile properties of B-free Ni3Al (Zr) alloys were investigated. The results indicate that the incompletely recrystallized and stress-relieved specimens show the most desirable ductility and ultimate tensile strength, and that the recrystallization treatment promotes susceptibility to the test environment of the alloys. It is found that the amount of ductile fracture is reduced by air for completely recrystallized specimens. The Auger analyses show that Zr atoms do not segregate to the grain boundaries(GBs) for specimens heat-treated at 1 100 degrees C, however Zr atoms segregate to the GBs for specimens heat-treated at 900 degrees C. These results imply that Zr-doping cannot suppress environmental embrittlement.
