| 摘 要： | 研究了合金元素Ｎｂ，Ｍｏ，Ｖ和Ｎｉ对Ｌａｖｅｓ相ＴｉＣｒ２室温力学性能的影响，测量了抗压断裂强度、抗压断裂应变、显微硬度及断裂韧性。结果表明，这些元素都能改善ＴｉＣｒ２的室温力学性能，其中Ｎｂ的作用较小，而Ｖ和Ｎｉ的作用较大，明显地降低抗压断裂强度和显微硬度，提高断裂韧性

| Abstract: | An investigation was undertaken to study the effects of adding Nb, Mo, V or Ni on the room temperature mechanical properties of the Laves phase TiCr 2. The compressive fracture strength, the compressive fracture strain, microhardness and fracture toughness were determined for the unalloyed and alloyed TiCr 2. Results show that the addition of alloying elements Nb, Mo, V or Ni has good effects on mechanical properties of TiCr 2 at room temperature. Among them, Nb has less effects, while V and Ni have stronger effects, i.e., obviously decrease the compressive fracture strength and microhardness of the Laves phase TiCr 2, and increase its fracture toughness. |
