Abstract

A two-phase transition zone of alpha-beta brass forms as a result of the melting of beta brass on alpha brass single crystal substrates. Specialized heat-treatments can convert this transition zone into a duplex crystal region of alpha-beta brass, or eliminate this region resulting in a sharp boundary between alpha and beta crystals. Specimens prepared by these treatments were deformed in uniaxial tension to study the initiation of plastic deformation and its propagation across the phase boundary. Although the phase boundary initially poses a resistance to the approaching slip, its effectiveness as a barrier depends on the crystallographic relationships between alpha and beta crystals. No void formation was observed at the boundaries.
