一种钛钼镍合金铸锭的制备方法
摘要：
一种钛镍钼合金铸锭的制备方法，特征在于添加了一种镍钼中间合金(钼元素质量百分含量20～35％)，钛钼镍合金铸锭的生产步骤为：采用海绵钛、镍钼中间合金或Ti-Mo中间合金配料，原料混匀后首先将其压制成电极块，再使用等离子弧等焊接方式将电极块焊接成自耗电极，经两次真空自耗电弧熔炼得到钛钼镍合金铸锭。本发明生产的钛钼镍铸锭，化学成分均匀、稳定，其化学成分偏差小于0.15％，无偏析和高密度夹杂冶金缺陷。本发明适用于生产冶金质量要求高的钛钼镍合金铸锭。
摘要（英）：

A Ti-Mo-Ni alloy ingot preparation method is characterized in that Ni-Mo intermediate alloy (the mass proportion content of Mo element is 20-35%) is added, the production steps of the Ti-Mo-Ni alloy ingot include that: titanium sponge, Ni-Mo intermediate alloy or Ti-Mo intermediate alloy are mixed uniformly and pressed into electrode blocks, the electrode blocks are welded into consumable electrodes through welding modes such as plasma arc, and the Ti-Mo-Ni alloy ingot is prepared through twice vacuum consumable electric arc smelting. The Ti-Mo-Ni alloy ingot produced by the preparation method has uniform and stable chemical compositions, has the chemical composition deviation of being less than 0.15%, is segregation free and overcomes the defect of high density metallurgical inclusion. The invention is applicable to producing the Ti-Mo-Ni alloy ingot with high metallurgical quality requirement.
