Abstract A superconducting metal alloy is formulated from 10- 50 at % Ti, 20-50 at % Nb, 10- 40 at % Zr and 5- 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.
A METHOD OF WORKING AND TREATING TI-NB-ZR-TA SUPERCONDUCTING ALLOY CONSISTING OF 10-50AT%TI, 20-50AT%NB, 10-4OAT%ZR AND 5-12AT%TA TO ACHIEVE A FINE AND NONHOMOGENEOUS STRUCTURE WHICH COMPRISES THE STEPS OF: FORMING A B SOLID SOLUTION OF SAID TI-NB-ZR-TA ALLOY BY HEATING THE ALLOY TO A TEMPERATURE WITHIN THE B SOLID SOLUTION RANGE; COOLING AND COLD WORKING SAID HEATED TI-NB-ZR-TA ALLOY; HEATING SAID COLD WORKED ALLOY TO A TEMPERATURE WITHIN THE (B''+B") PHASE REGION AND THEN COOLING SAID HEATED (B''+B") ALLOY TO MAINTAIN THE PERITECTOID STRUCTURE; COLD WORKING THE PERITECTOID ALLOY, FORMING A MULTI-PHASE B''+B"+A (W) EUTECTOID ALLOY STRUCTURE BY HEATING SAID PERITECTOID ALLOY TO A TEMPERATURE
