ABSTRACT:
A method of manufacturing a nickel-titanium-beryllium alloy wire, comprising the steps of preparing a nickel-titanium alloy consisting essentially of nickel (Ni) 50 to 40% by weight and titanium (Ti) 40 to 50% by weight, with a portion of either the Ni or Ti being replaced by from 0.005 to 0.5% beryllium (Be), brining the nickel-titanium-beryllium alloy to a molten state, and jetting a melt of the alloy into a liquid flow, formed as a laminar flow, on the internal surface of a rotating drum so as to cool and solidify the nickel-titanium-beryllium alloy from its molten state into a fine wire at an average cooling rate in the range of 10.sup.2 to 10.sup.4 C/sec.
