- 摘要:
- 采用镶铸法制备了ZTC4/H13双金属复合铸件试样,从复合铸件内部质量、复合界面的结合情况及材料力学性能三方面进行了研究。结果表明,复合铸件内部未发现裂纹、缩孔等铸造缺陷,界面结合方式属于机械结合,H13合金经熔炼浇注及热等静压后强度有所降低,断后伸长率有所提升。The sample of ZTC4/H13 bimetallic composite casting was prepared by inlay casting method. The internal quality of the composite casting, the bonding of the composite interface and the mechanical properties of the material were studied. The results show that no cracks, shrinkage holes or other casting defects are found in the composite casting, the interface bonding mode is mechanical bonding, the strength of H13 alloy will decrease after smelting casting and hot isostatic pressing, and the elongation after fracture will increase.
