| Abstract: | In order to reduce the elastic modulus and improve the damping performance of medical titanium alloy, TZNM alloy was smelted by water-cooled copper crucible induction melting technology, and the sample was treated with solution treatment. Then, the microstructure and mechanical properties of TZNM alloy before and after solution treatment were studied by scanning electron microscope, transmission electron microscope, chemical analysis method, Vickers hardness test and damping test. The results show that TZNM alloy has a good overall melting effect, and its chemical composition meets the expected design. The phase structure is a typical two-phase α+β type titanium alloy, and the microstructure in as-cast is that strip martensite α is distributed on the β matrix, and the martensite α′after solution treatment is fine needle. In addition, the Vickers hardness of TZNM alloy after solution treatment is 361 HV, which is 13.6% higher than that in as-cast state. As the strain amplitude increases, the internal friction of TZNM alloy gradually increases, and the overall damping performance before and after solution treatment is improved to varying degrees. |
