摘要:
为了研究钛合金中常用β合金元素Mo、V、Cr等对β相合金化的影响，通过设计制备一系列不同元素含量的Ti-Mo、Ti-V、Ti-Cr二元β型钛合金，分析了含单一合金化元素的β型钛合金的显微组织、硬度及室温拉伸性能。结果发现：随着合金中β稳定元素含量的增加，所有二元合金的晶格常数及晶粒尺寸都呈减小的趋势，其中元素Cr具有最强烈的减小晶格常数效应，而元素Mo对晶粒细化的效果最显著。成分为Ti-xV、Ti-xCr的β相的拉伸强度随元素含量增加的变化规律与硬度变化相似，先减小后增加。Ti-xMo拉伸强度则随元素含量的增加强度升高。元素Cr对β相的强化效果高于Mo和V。
Abstract:
In order to study the influence of usual beta elements Mo, V, Cr in titanium alloy on alloying effect of beta phase, a series of binary beta titanium alloys such as TiMo,TiV and TiCr were designed and prepared. The microstructure, hardness and room temperature tensile property of beta titanium alloys containing single beta element were tested. Results showed that: With the increase of the content of beta alloying elements, the lattice constant and grain size of all binary alloys decrease; the element Cr has the most strongly reduced lattice constant effect, while the effect of element Mo on grain refinement is most notable; The tensile strength and hardness of β phase of TixV and TixCr alloys firstly decrease, then increase with the content of beta elements increasing, and the tensile strength of β phase of TixMo alloy increases linearly; The strengthening effect of element Cr for beta phase is higher than that of Mo and V.
