Abstract
Ni-45wt% Ti(Ni-50at% Ti) alloy was cast into Magnesia cement molds and phosphate-bonded investment molds, using an Argon-arc pressure casting machine and a Cu crucible.
The castings (bars) by Magnesia cement molds have larger elongation and rougher surfaces, than those by phosphate-bonded investment molds.
All castings bent at 0℃ showed shape memory effect. Some of the castings were broken on bending at 0℃.
