| 英文摘要 | Co-based alloy has high strength, good corrosion and wear resistance, and is widely used in aviation industry, nuclear industry. The cast Co-based alloys has high hardness brittleness, but the toughness is low, which limits its wide use. The CoCrW alloy prepared by powder metallurgy process has high toughness, at the same time, the mechanical properties of the CoCrW alloy can be changed by heat treatment. In this work, the effect of solid solution treatment on the microstructure and mechanical properties of the hot pressed alloy was studied by SEM, XRD and TEM, hardness test, room-temperature tensile and wear experiment. The results show that the microstructure of the as-hot pressed and solid solution state CoCrW alloy are both composed of M23C6, M6C, CrCo intermetallic compounds and gamma-Co matrix, the contents of M23C6 and prior particle boundaries decrease remarkably after solution treatment, meanwhile, the toughness and wear resistance of the alloy are improved. With the increase of solid solution temperature and time, the hardness and tensile strength at room temperature of CoCrW alloys increase first and then decrease. |
