Abstract We report dealloying of Ti60Ta40 (wt.%) in molten copper, eutectic Cu28Ag72 alloy and Cu20Ag40Bi40 alloy for the fabrication of ultrafine Ta ligament structures across a 1-mm thick section. When dealloyed in molten Cu and Cu20Ag40Bi40, the melt temperature dictated the length scale of Ta ligaments, which decreased exponentially with decreasing temperature. Conversely, dealloying in molten eutectic Cu28Ag72 alloy led to complex Ta ligament structures due to the enhanced surface diffusivity of Ta by Ag. Ultrafine (

钛钽 (Ti-Ta) 合金液态金属脱合金以制造超细 Ta 韧带结构：熔融铜 (Cu) 和铜基合金的比较研究

摘要 我们报告了在熔融铜、共晶 Cu28Ag72 合金和 Cu20Ag40Bi40 合金中对 Ti60Ta40 (wt.%) 进行脱合金，用于制造 1 毫米厚截面的超细 Ta 韧带结构。当在熔融的 Cu 和 Cu20Ag40Bi40 中脱合金时，熔融温度决定了 Ta 韧带的长度尺度，它随着温度的降低呈指数下降。相反，在熔融共晶 Cu28Ag72 合金中脱合金会导致复杂的 Ta 韧带结构，因为 Ag 增强了 Ta 的表面扩散率。超细（
