-- Ti-Ni-Hf based shape memory alloy and method for hot forming thereof

摘要

The titanium-nickel-hafnium shape memory alloy according to the present invention is obtained by homogenizing a titanium (Ni) -haponium (Hf) alloy ingot ingot and subjecting the homogenized titanium (Ti) -nickel Ti-Ni-Hf-based alloy ingot is prepared from a Ni-hafnium-Hf-based alloy ingot and then subjected to canning in order to suppress high-temperature oxidation, And is produced by pressure molding.
