為了研究鈦合金中常用β合金元素Mo、V、Cr等對β相合金化的影響，通過設(shè)計(jì)制備一系列不同元素含量的Ti-Mo、Ti-V、Ti-Cr二元β型鈦合金，分析了含單一合金化元素的β型鈦合金的顯微組織、硬度及室溫拉伸性能。結(jié)果發(fā)現(xiàn)：隨著合金中β穩(wěn)定元素含量的增加，所有二元合金的晶格常數(shù)及晶粒尺寸都呈減小的趨勢，其中元素Cr具有最強(qiáng)烈的減小晶格常數(shù)效應(yīng)，而元素Mo對晶粒細(xì)化的效果最顯著。成分為Ti-xV、Ti-xCr的β相的拉伸強(qiáng)度隨元素含量增加的變化規(guī)律與硬度變化相似，先減小后增加。Ti-xMo拉伸強(qiáng)度則隨元素含量的增加強(qiáng)度升高。元素Cr對β相的強(qiáng)化效果高于Mo和V。

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 TiMo,TiV and TiCr 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 TixV and TixCr alloys firstly decrease, then increase with the content of beta elements increasing, and the tensile strength of β phase of TixMo alloy increases linearly; The strengthening effect of element Cr for beta phase is higher than that of Mo and V.
