Influence of ultrasonic treatment on formation of primary Al3Zr in Al–0.4Zr alloy (2017)
Journal Article
WANG, F., ESKIN, D., CONNOLLEY, T., & MI, J. W. (2017). Influence of ultrasonic treatment on formation of primary Al3Zr in Al–0.4Zr alloy. Transactions of Nonferrous Metals Society of China, 27(5), 977-985. https://doi.org/10.1016/S1003-6326%2817%2960115-8

© 2017 The Nonferrous Metals Society of China The effect 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 liquid... Read More about Influence of ultrasonic treatment on formation of primary Al3Zr in Al–0.4Zr alloy.
