Ｔａ－１０Ｗ、Ｔａ－１２Ｗ、Ｔａ－１３Ｗ和Ｔａ－１５Ｗ４种Ｔａ－Ｗ二元合金经电子束熔炼，最终轧制成７．０ｍｍ和１．０ｍｍ厚的板材，并经再结晶热处理。室温力学性能试验表明，合金强度和硬度随Ｗ含量增加线性增长，合金延性随Ｗ含量增加下降不显著，意味着几种高Ｗ含量的Ｔａ－Ｗ合金既有高强度，又有良好的塑性。合金强度与硬度之间亦有线性关系，遵从ｂｃｃ金属的绝热固溶强化模型，但高Ｗ含量合金的实测硬度低于模型计算硬度值，说明合金仍可进行冷加工。在同样条件下，几种合金同纯Ｔａ相比有均匀的显微组织，保证了合金有良好的韧性。对合金的强化机制也作了一定的讨论。
Ta-10W, Ta-12W, Ta-13W and Ta-15W four kinds of Ta-W binary alloy by electron beam melting, and finally rolled into 7.0mm and 1.0mm thick plate, and recrystallization heat treatment. Mechanical tests at room temperature show that the strength and hardness increase linearly with the increase of W content, and the ductility of the alloy does not decrease significantly with the increase of W content, indicating that several high W content Ta-W alloys have both high strength and good ductility. There is also a linear relationship between the strength and hardness of the alloy, adhering to the bcc metal adiabatic solution strengthening model, but the measured hardness of the alloy with high W content is lower than the model calculated hardness value, indicating that the alloy can still be cold working. Under the same conditions, several alloys have uniform microstructure compared with pure Ta, which ensures the alloy has good toughness. The strengthening mechanism of the alloy also made some discussion.
