Journal Article
Mi, J., Connolley, T., Eskin, D., & Wang, F. (2016). Effect of ultrasonic melt treatment on the refinement of primary Al3Ti intermetallic in an Al–0.4Ti alloy. Journal of Crystal Growth, 435, 24-30. https://doi.org/10.1016/j.jcrysgro.2015.11.034

High intensity ultrasonic melt treatment was applied to an Al–0.4 wt% Ti alloy over three selected temperature ranges: 810 to 770 °C (above liquidus), 770 to 730 °C (across liquidus), and 730 to 690 °C (below liquidus). The size and morphology of the... Read More about Effect of ultrasonic melt treatment on the refinement of primary Al3Ti intermetallic in an Al–0.4Ti alloy.
