摘　　要：Al-Sc alloys with high Sc contents are served as sputtering targets for making high-performance piezoelectric devices.The micro structure of these alloys would affect the sputtering process and the final quality of the functional devices.In this study,the microstructure in as-c as ted Al-20%Sc(in atomic ratio)alloys is characterized and the feathery Al3Sc grains with twin relationships are reported for the first time.The crystallographic features of twined structures and growth directions are quantitatively analyzed by electron backscatter diffraction(EBSD)technique.
