研究不同規(guī)格的Ti-45Nb合金絲材的顯微組織和力學性能。結果表明：隨著Ti-45Nb合金絲材尺寸的增大，其抗拉強度不斷降低，但屈服強度和剪切強度不斷增加，而顯微組織以及拉伸塑性的變化幅度不是很明顯；經熱暴露后的Ti-45Nb合金絲材，拉伸強度明顯增加，但拉伸塑性的下降也比較明顯；不同規(guī)格的Ti-45Nb合金絲材經過冷頂鍛測試后的樣品表面均沒有宏觀裂紋萌生，表明材料具有良好的冷成形性能。

The microstructures and mechanical properties of Ti-45Nb alloy wires with different dimensions were investigated. The results show that, with increasing the dimensions of Ti-45Nb alloy wires, the tensile strength of Ti-45Nb alloy decreases gradually, but the yield strength and tear strength increase gradually, the microstructures and tensile plasticity do not change obviously. After thermal exposure, the tensile strength increases obviously, but the tensile plasticity decreases. There is no macroscopic cracking initiation when Ti-45Nb alloy wires with different dimensions are cold upset, which indicates that the Ti-45Nb alloy wires have good properties of cold deformation and forming.
