Theory on mechanism of phase-transformation in electrolytic alloys

Abstract

In this paper a brief account has been furnished about Banerjee's theory on mechanism of phase-transformation in electrolytic alloys. Banerjee during the course of his investigation on the influence of various factors on the composition of electro-deposited brass observed a number of interesting phenomena based on which he formulated his theory. Subsequent workers have confirmed Banerjee's view that the phase-structure of an alloy deposit is to be considered in the light of the excess energy imparted to the discharged ion by the imposed cathode potential. The formation of metastable phases in electro-deposited alloys has been found to be in accordance with Banerjee's theory. (Dr. T.
