| Abstract: | AlTiB grain refiner was prepared by fluoride and salt method.The effects of ultrasonic vibrations on the microstructures of the grain refiner were studied by OM.Experimental results indicate that ultrasonic vibrations can solve the problem of agglomeration of nucleating phase.Ultrasonic vibrations affects distributing of the TiAl_3 and TiB_2,and grain refiner exhibited good grain refining performance for commercially pure Al. |
