| 摘 要： | 研究了喷射成形高速钢T15沉积坯的部分力学性能及微观组织.结果表明,喷射成形制备的高速钢,晶粒细小,无宏观偏析,平均体密度为8.208g/cm3,三点抗弯强度达到1860 MPa.但通过SEM观察发现沉积坯内存在局部显微疏松,为了进一步提高材料性能,需要对高速钢沉积坯做热等静压等后续热加工.

| Abstract: | The microstructure and some mechanical properties of high speed steel(HSS) T15 preform made by spray forming were researched.The result indicated that the high-quality perform of HSS T15 exhibited high-density,refined grains and segregation-free macrostructure.The average density of perform before heat treatment(HT) is 8.208g/cm3 and three-point bending strength reaches 1860 MPa.All of them show that spray forming is an appropriate technics to fabricate high-property HSS.But some local porosities were found... |
