在不同的铸造条件下制备了Ni-43.5wt% Ti合金棒材。在堇青石坩埚中熔化并在磷键熔模中铸造的试样强度和伸长率低于在铜坩埚中熔化并在磷键熔模中铸造的试样。所有铸件在室温下均表现出超弹性。可恢复应变的上限约为1.8%。用该合金制成的铸扣与模具贴合性好，柔韧性好，具有超弹性。
Rods of Ni-43.5wt% Ti alloy were prepared under various casting conditions. Specimens which were melted in a cordierite crucible and cast in a phosphate-bonded investment mold had less strength and elongation than those melted in a copper crucible and cast in a phosphate-bonded investment mold. All castings exhibited superelasticity at room temperature. The upper limit of recoverable strain was about 1.8%. The cast clasps made of the alloy had good fit to a die, good flexibility, and superelasticity.
