Iron-nickel-titanium-cobalt alloy with shape memory effect and pseudo-elasticity, and method of producing the same

摘要

An alloy with a shape memory effect and a pseudo-elasticity which exhibits a thin-plate martensitic structure and consists of 32-34 wt.% of nickel, 3-6 wt.% of titanium, 10-15 wt.% of cobalt and the remainder of iron can be made by heating a starting alloy to a temperature between 900°C to 1,200°C and then aging at a temperature between 500°C and 800°C.
