    摘要:

    研究了一種近β鈦合金在不同熱處理?xiàng)l件下的性能及顯微組織。結(jié)果表明：該合金在不同的熱處理工藝下可獲得不同的強(qiáng)度、塑性匹配。合金在α+β區(qū)固溶后時(shí)效可獲得強(qiáng)度在1200～1500 MPa之間的不同的強(qiáng)度級(jí)別，并且具有很好的塑性。合金的力學(xué)性能主要受初生α相的形態(tài)控制。該合金還具有一般近β鈦合金的時(shí)效特征, 即隨著時(shí)效溫度的升高, 強(qiáng)度降低, 塑性升高

    Abstract:

    Microstructure and properties of a near β titanium alloy after different heat treatments were studied. The results show that different match of strength and plasticity can be obtained by different heat treatments. After α+β solution and aging treatment, excellent strength (ultimate tensile strength of 1200-1500 MPa) and plasticity can be achieved. The mechanical property of the alloy is mainly controlled by the shape of primary α. The alloy also has the aging characteristics of common near-β titanium alloy, i.e. its strength decreases and plasticity increases with aging temperature rising
