Influence of cold and hot pressing on densification behaviour of titanium alloy powder Ti6Al4V
This paper analyzes three ways of processing Ti-6%Al-4%V titanium alloy powders: compacting specimens in 25 mm diameter under different pressures by a floating die and sintering in a vacuum furnace, producing axially symmetric PM compacts in a compacting device with a plastic die, hot compacting a powder in a die under protective argon atmosphere. The powder was produced by the following two methods: HDH (hydride-dehydride) and gas atomization (GA). A special device, allowing the simultaneous compaction and sintering of powder under protective argon atmosphere, was constructed. A solid material was obtained from Ti6Al4V titanium alloy powders produced by GA. It seems that the proposed technology of compaction under argon atmosphere could be used to manufacture products from titanium alloys on the industrial scale more economically since it combines compaction and sintering and does not require costly equipment.
