Abstract: This paper introduces the preparation of TiH₂ powder compacts and TiH₂-6Al-4V alloy powder compacts by die compacting.The formability and green density variation as a function of compaction pressure are researched.Without any binder,compacts are obtained by die compacting.The results show that the forming of coarse TiH₂（40μm）powder is easy,but the forming of milling 30 min TiH₂ powder is difficult,and the latter compact is prone to crack.The longer milling the time is,the more difficult forming is.The green densities of coarse TiH₂（40μm）powder,high energy ball milling（HEM）30min TiH₂ powder and TiH₂-6Al-4V powder increase with the pressure increasing.Under the same compaction pressure,the green density of coarse TiH₂ powder（40μm）is higher than that of ball milling 30min TiH₂ powder.
