摘要
Abundant growth twin boundaries are found and characterized in two bulk eutectic Cu-Ag alloys that can be obtained conveniently. The statistical electron backscattering diffraction results show that both hetero-twin and cube-on-cube orientation relationships coexist in the eutectic Cu-Ag alloy. The tensile strength of the eutectic alloy increases with a decrease in the layer thickness of the Cu/Ag phase. This study provides a potential way to produce bulk eutectic Cu-Ag alloy with abundant twin boundaries that offers a combination of high strength and high ductility. (C) 2011 Acta Materialia Inc.
