本文报道了在国产新型超低间隙钛合金低温拉伸研究中发现的多处颈缩现象，通过多处颈缩的力学模型和透射电镜（ＴＥＭ），分析了这种金属力学现象发生的可能原因．
In this paper, we report the occurrence of multiple necking phenomena in the research of the new ultra-low gap titanium alloy produced at home and abroad. The possible causes of the phenomenon of metal mechanics are analyzed by the mechanics model with multiple necks and the transmission electron microscope (TEM) .
