Abstract
The manufacturing methods according to the present teachings provide shape memory alloy products having both a uniform composition and a precise shape memory recovery temperature. In this manufacturing method, raw material powders (e.g., Ti and Ni powders) may be precisely mixed. Next, a compound may be synthesized from the raw material powder mixture using a combustion synthesis method. The combustion synthesized compound may be melted and cast into a desired shape (e.g., a shape of the final product or a shape close to that of the final product).
Claims5
A method of making a shape memory alloy product, comprising:
- mixing raw material powders at a predetermined ratio, the raw material powders comprising Ni and Ti powders,
- synthesizing a compound from the raw material powders by a combustion synthesis method,
- melting the combustion synthesized compound, and
- casting the melted compound into the desired shape by a lost wax method.
