研究了添加Fe对Ti-V-Al-Fe合金马氏体相变和形状记忆行为的影响。微量Fe显著降低了Ti-V-Al合金的马氏体相变温度,增强了合金的形状记忆效应。Fe含量最佳的Ti-13V-3Al-1Fe合金在预应变为6%时,可恢复应变最大,为5.8%,最大恢复应力为250 Mpa。同时,Ti-13V-3Al-1Fe合金具有高达30%的延伸率。
Effects of Fe addition on martensitic transformation and shape memory behavior of Ti-V-Al-Fe alloys were investigated. A little amount of Fe addition reduces martensitic transformation temperature rapidly and enhances shape memory effect of Ti-V-Al alloy. Alloy with an optimal Fe content, which is Ti-13V-3Al-1Fe, shows the largest recoverable strain of 5.8% and highest recovery stress of 250 MPa when pre-strain is 6%. Meanwhile, Ti-13V-3Al-1Fe alloy has a large elongation of 30%.
