Abstract : A novel alloy composition consisting essentially of 10 from about 50% to about 70% nickel by weight and correspondingly from about 50% to about 30% titanium by weight is described. The said alloy has the structure of a TiNi phase in combination with a TiNi3 phase dispersed in a TiNi matrix within a temperature range of from about 500 C to about -75 C and having the properties of being paramagnetic, of retaining hardness throughout said temperature range and of being corrosion resistant. A novel alloy composition consisting essentially of 20 from 52% to about 56% nickel by weight and correspondingly from about 48% to about 44% titanium by weight is described. The said alloy having the structure of a substantially TiNi phase within a temperature range of from about 500 C to about -75 C and having the properties of being paramagnetic, of being highly vibration damping at about room temperature and having the capability of being plastically deformed at about room temperature and retaining the deformed shape until heated to a higher temperature whereupon the prior nondeformed condition will be reassumed. A novel alloy composition consisting essentially of from about 56% to about 64% nickel by weight and correspondingly from about 44% to about 36% titanium by weight is described. The said alloy having the structure of a substantially TiNi3 phase dispersed in a TiNi matrix within a temperature range of from about 450 C to about -75 C and having the properties of being paramagnetic, of high hardness upon heat treatment, of being abrasion and corrosion resistant and capable of being hot wrought into useable shapes prior to hardening.
