Trans. Nonferrous Met. Soc. China 27(2017) 977-985 Influence of ultrasonic treatment on formation of primary Al3Zr in Al-0.4Zr alloy Feng WANG1, D. ESKIN1,2, T. CONNOLLEY3, Jia-wei MI4 1. Brunel... of ultrasonic treatment on the formation of primary Al3Zr was investigated by applying ultrasound to an Al-0.4Zr alloy. Three temperature ranges were selected, i.e., 830 to 790 °C (above liquidus), 790 to 750......
