Abstract
Ti-5Al-2.5Sn ELI alloy is one of the most promising cryogenic material whose use is expected to spread in near future. The alloy has been used for cryogenic application. But, cast parts are scarecely applied, and no data is available of mechanical properties of Ti-5Al-2.5Sn ELI cast material. Casting techniques is a part of the most important things to produce the complicated shapes and to save cost of titanium parts. The present work reports of the mechanical properties of the alloy tested both at room temperature and under cryogenic conditions. The materials were casted in rammed graphite mould and HIP'ed and heat treated under some conditions.
