种粉末冶金钛合金的制备方法

本发明涉及种粉末冶金钛合金的制备方法，包括下述的步骤：以TiH粉、Ti粉和其他合金元素为原料，混合均匀并压制成型，其中TiH的加入量占原料总质量的3～25％；在高真空环境下加热使得TiH分解，保持在氢气气氛烧结；然后降温到750～1000℃，抽真空除氢；最后，冷却后得到粉末冶金钛合金产品。本发明以氢化钛的形式向粉末冶金钛合金中加入H元素，并通过控制氢化钛的量来控制H的加入量。同时通过控制氢气氛烧结钛合金的除H温度来调节烧结钛合金的组织结构，以得到高性能的钛合金。相比未添加氢化钛，得到的合金的密度增加，抗拉强度增大。 The invention relates to a preparing me...

The preparing method includes the following steps that TiH2 powder, Ti powder and other alloy elements serve as raw materials and are evenly mixed to be subject to compression molding, wherein the adding amount of TiH2 accounts for 3%-25% of the total mass of the raw materials; the TiH2 is heated in a high-vacuum environment to be decomposed and is sintered in a hydrogen atmosphere; then the temperature is reduced to 750 DEG C to 1000 DEG C, and vacuum pumping is conducted for hydrogen removing; and finally, the powder metallurgy titanium alloy product is obtained after cooling. According to the preparing method, the element H is added into the powder metallurgy titanium
