A METHOD OF INCREASING THE CRITICAL CURRENT DENSITY OF A HARD SUPERCONDUCTING ALLOY WHICH COMPRISES MIXING SAID ALLOY IN THE LIQUID STATE WITH AN ADDITIVE SELECTED FROM THE GROUP OXYGEN, CARBON, NITROGEN, BORON, AND HYDROGEN, HOMOGENIZING THE RESULTANT MIXTURE AT A TEMPERATURE BELOW THE MELTING POINT OF SAID ALLOY TO EFFECT UNIFORM DISTRIBUTION OF SAID ADDITIVE, COOLING THE RESULTANT HOMOGENIZED ALLOY TO INDUCE FORMATION O A FINELY DIVIDED PRECIPITATED PHASE CONTAINING SAID ADDITIVE AND THEREAFTER REDUCING SAID ALLOY TO A DESIRED GAUGE SIZE.
