Influence of the Volume Fractions of the Phases on the Deformation of (α+β) Brass

Abstract

The relative deformations of the phases were studied, after 20, 40, 60, and 80 per cent. reductions in area by wire drawing in duplex brasses of various compositions, using as a measure of the degree of deformation the temperature at which recrystallization began. In alloys containing more than about one-third by volume of the hard P phase, crystals of both phases deformed to the same extent, but in alloys containing 10 or 20 per cent. by volume of the β phase, the heavier deformation always occurred in the soft a phase. The mode of recrystallization of the phases varied with the degree of deformation and the volume proportion of the phases.
