THE METHOD OF FORMING AN ELECTRICAL UNIT WHICH COMPRISES (A) FORMING AN ASSEMBLY OF A BODY OF MATERIAL CLOSELY CONTAINED WITHIN A SHEATH, SAID MATERIAL COMPRISING A PLURALITY OF ELEMENTS OF SUCH COMPOSITIONS AND PRESENT IN SUCH AMOUNTS AS TO BE CAPABLE OF FORMING INTERMETALLIC COMPOUNDS WITH ONE ANOTHER, SAID SHEATH COMPRISING PHYSICALLY WORKABLE, ELECTRICALLY CONDUCTIVE MATERIAL COMPATIBLE WITH SAID INTERMETALLIC COMPOUND; (B) RAISING THE TEMPERATURE OF SAID MATERIAL AND PHYSICALLY REDUCING THE THICKNESS OF SAID ASSEMBLY TO A DEGREE SUFFICIENT TO CAUSE SAID ELEMENTS TO FORM SAID INTERMETALLIC COMPOUND, THEREBY PRODUCING A CORE OF SAID INTERMETALLIC COMPOUND IN INTIMATE PHYSICAL AND ELECTRICAL CONTACT WITH SAID SHEATH, AND (C) REMOVING SAID SHEATH FROM A PORTION OF SAID CORE, THE REMAINING PORTION OF SAID SHEATH CONSTITUTING A TERMINAL IN GOOD ELECTRICAL CONNECTION WITH SAID INTERMETALLIC COMPOUND.
