A study was made of high-current samples which had been processed by means of melt-texturing, using the liquid-phase removal method. The misorientation (kink angle) of the a-b planes across each boundary was measured. The results indicated that high-angle grain boundaries predominated in the samples. The high current transport capacity of the bulk polycrystalline samples indicated that the liquid-phase removal method was capable of producing good grain boundary links which permitted the passage of a high currents.
