Abstract—Conditions for preparing radiation-resistant titanium alloys by electric-arc melting with a nonconsumable tungsten electrode in an argon atmosphere and subsequent cutting into planar samples and vacuum heat treatment of them are described. Titanium alloys with niobium, molybdenum, zirconium, and aluminum are prepared using several-stage electric-arc melting. The homogeneity of chemical element distribution in the alloy samples is estimated by energy dispersive mapping. To determine the effect of alloying elements and heat treatment temperature (700, 800, and 900°C), the mechanical properties of the alloys are analyzed. Heat treatment at 900°C is found to increase the ultimate strength to 766 MPa.

摘要—介绍了在氩气气氛中用非自耗钨电极电弧熔化制备抗辐射钛合金，然后切割成平面样品并对其进行真空热处理的条件。使用多阶段电弧熔化制备具有铌、钼、锆和铝的钛合金。通过能量色散映射估计合金样品中化学元素分布的均匀性。为了确定合金元素和热处理温度（700、800 和 900°C）的影响，分析了合金的机械性能。发现 900°C 的热处理可将极限强度提高到 766 MPa。
