    摘要:

    研究骨科植入用TLM鈦合金的相轉(zhuǎn)變過程及其對合金力學性能的影響。結(jié)果表明,TLM鈦合金固溶后的顯微組織為β相和少量細長的α″相,合金經(jīng)低溫300 ℃至500 ℃時效的過程中,α相的形成經(jīng)歷β →ω →α、α″ →α 2個過程,微觀組織揭示出α″馬氏體對亞穩(wěn)ω相的形成具有一定的阻礙作用。同時TLM鈦合金中相結(jié)構(gòu)對降低彈性模量的程度由大到小的順序為:ω>α″>α;相結(jié)構(gòu)對提高強度的作用由大到小的順序為:ω>α>α″;而相結(jié)構(gòu)對延伸率的提高由大到小的順序為:α″>α>ω。

    Abstract:

    Phase transformation and mechanical properties of TLM titanium alloy for orthopaedic implant application were studied. The results show that a small amount of slender α″ phase exists in the β matrix after solution treating and water quenching. The formation of α phase goes through two procedures during the aging treatment from 300 oC to 500 oC, one is β→ω→α, and the other is α″→α. While the micrographs reveal that α″ martensite hinder the nucleation and growth of metastable ω phase. The effect of the phase structures on reducing the elastic modulus is in the order of ω>α″>α, and the effect on improving the strength is in the order of ω>α>α″, and vice versa for improving the elongation of TLM alloy.
