Method of treating Ti--Ni--Zr--Ta superconducting alloys

Patent ·
OSTI ID:7144121
A superconducting metal alloy is formulated from 10 to 50 at.% Ti, 20 to 50 at.% Nb, 10 to 40 at.% Zr and 5 to 12 at.% Ta. A Ti-Nb-Zr-Ta superconducting alloy with a fine, non-homogeneous structure is obtained by forming a ..beta.. solid solution of said Ti-Nb-Zr-Ta alloy by heating the alloy to a temperature within the ..beta.. solid solution range, cooling and then cold working said heated alloy, heating said cold worked alloy to a temperature within the (..beta..' + ..beta..'') alloy to maintain the peritectoid structure, cold working the peritectoid alloy, heating said peritectoid alloy to a temperature within the eutectoid range to form a multiphase eutectoid alloy structure and then cooling said eutectoid alloy and finally cold working the eutectoid alloy. 1 claim, 8 figures.
