    摘要:

    通過成分微調(diào)在Ti-6Al-4V合金基礎(chǔ)上發(fā)展了一種基于Ti—Al—V-Si四元系TC4S兩相鈦合金。研究表明，添加少量合金元素Si，并對Al，V元素含量進(jìn)行微調(diào)，使新合金的主要力學(xué)性能得到提高，強(qiáng)度、塑性和斷裂韌性得到良好匹配，從而滿足了設(shè)計(jì)要求。TC4S合金可以在不明顯降低塑性和韌性的前提下，比Ti-6Al-4VELI合金的強(qiáng)度提高80MPa-100MPa。

    Abstract:

    A new alloy belonging to Ti-AI-V-Si system has been developed on the base of Ti-6Al-4V, designated as TC4S. Experimental test results show that mechanical properties of TC4S have been improved evidently by proper adjusting the contents of Al and V, adding small amount of Si when compared with conventional Ti-6Al-4V alloy. The satisfied match among the strength, the ductility and the fracture toughness of the alloy has been reached, and meets the requirements of the design. The strength of TC4S alloy can be increased by 60 MPa-100 MPa on the condition of the slight damaging its plasticity and toughness, compared with Ti-6Al-4V ELI.
