美国衣阿华州立大学研究人员研制出了一种具有高导电性和高拉伸强度的 Cu-Ta 合金并获得专利权。可消耗的铜电极和钽电极以同样的速度熔化形成均匀的合金,钽粒子随机地沉积在铜基本中,Cu、Ta 比取
Iowa State University researchers developed a high conductivity and high tensile strength of Cu-Ta alloy and patented. The consumable copper and tantalum electrodes melt at the same rate to form a uniform alloy. The tantalum particles are randomly deposited in the copper matrix. The Cu and Ta ratios
