用常规拉伸和Ｈｏｐｋｉｎｓｏｎ拉杆技术，研究具有近全片层组织形变Ｔｉ－４７ＡＩ－ＺＭｎ－２Ｎｂ合金１８０Ｋ下静态（１０－５──１０－１ｓ－１）和动态（２０－１０３ｓ－１）拉伸性能及其受硼的影响，发现Ｔｉ－４７ＡＩ－２Ｍｎ－２Ｎｂ和Ｔｉ－４７ＡＩ－２Ｍｎ－２Ｎｂ－１Ｂ合金１８０Ｋ下的拉伸强度均比室温高，静态（１０－５──１０－１ｓ－１）时与应变速率之间呈单对数线性关系，动态（１０—１０３ｓ－１）时呈线性关系．１．０Ｂ原子分数，％）仍能明显提高合金的静态和动态拉伸强度，但对拉伸塑性和断裂方式影响不大，与室温结果非常相似
Using conventional tensile and Hopkinson tie bar technology, we studied the mechanical properties of the Ti-47AI-ZMn-2Nb alloy with near full-slice deformation (10-5─10-1s -1) and dynamic (20-103s -1) Tensile properties of Ti-47AI-2Mn-2Nb and Ti-47AI-2Mn-2Nb-1B alloy were all higher than those at room temperature and static (10-5─10-1s- 1) and the strain rate showed a single logarithmic linear relationship, dynamic (10-103s-1) showed a linear relationship. 1.0B atomic fraction,%) still can significantly improve the static and dynamic tensile strength of the alloy, but has little effect on tensile ductility and fracture mode, which is very similar to the result of room temperature
