A titanium, nickel and iron alloy within an area defined on a titanium, nickel and iron ternary phase diagram by a quadrilateral with its first corner at 49.1 atomic percent titanium, 47.3 atomic percent nickel and 3.6 atomic percent iron; its second corner at 49.1 atomic percent titanium, 48.8 atomic percent nickel and 2.1 atomic percent iron; its third corner at 50.2 atomic percent titanium, 46.8 atomic percent nickel and 3.0 atomic percent iron; and its fourth corner at 50.2 atomic percent titanium, 45.1 atomic percent nickel and 4.7 atomic percent iron, the martensitic transformation temperature of said alloy being such as to permit impartation of heat recoverability to an object formed thereof at a temperature above the boiling point of liquid nitrogen.
