Effect of Heat-treatment on the Mechanical Properties of Ni-Be Casting Alloy |
| |
| Abstract: | WT5”BZ]In this paper, the effects of heat treatment on the mechanical properties of the Ni Be casting alloy are investigated with tensile test、 hardness test、metallographic structure and scanning electron microscopy(SEM). The results show that the mechanical properties are affected largely by aging time and aging temperature, and it's found with SEM that there are fine toughness dens on the fracture surface of the Ni Be alloy. Through different heat treatment processes, three kinds of Ni Be alloy with different hardness (HRB87、HRC32、HRC51) are obtained, and their comprehesive properties are excellent. [WT5”HZ] |
