日本关西大学工程系研究了氧添加剂对从β-相区温度淬火的 Ti-(10～40)V,Ti-20V 和Ti-30V 合金比电阻和硬度的影响。用 X 射线衍射确定了室温下合金的相结构。X 射线相结构研究表明,Ti-V-0.3%O 合金与含～0.1%O 的Ti-V 合金没有明显不同。氧含量愈低则负温度下的钒含量范围的终点愈低。氧添加剂可使合金的电阻率提高,除15%V 合金外,氧添加剂还能提高合金的硬度。20%V 合金的硬度比其它合金小,这是由于在室温下隔热的ω相体积分数随氧添加量而减少。
The effect of oxygen additive on the specific resistance and hardness of Ti- (10-40) V, Ti-20V and Ti-30V alloys quenched from β-phase region was studied by Engineering Department, Kansai University. The phase structure of the alloy at room temperature was confirmed by X-ray diffraction. X-ray phase structure studies show that there is no significant difference between Ti-V-0.3% O alloy and Ti-V alloy containing ~ 0.1% O. The lower the oxygen content, the lower the endpoint of the vanadium content range at negative temperatures. Oxygen additives can improve the resistivity of the alloy, in addition to 15% V alloy, the oxygen additive can also increase the hardness of the alloy. The hardness of the 20% V alloy is less than that of the other alloys due to the decrease in the fraction of the ω phase insulating at room temperature with increasing oxygen loading.
