Abstract
The chemical composition, microstructure, and grain refining performance of high-quality Al–5Ti–1B master alloy were investigated. The results show that the content of alloying elements Ti and B in the Al–5Ti–1B master alloy is stable. The content of impurity elements Fe, Si, V, and K is very low. The microstructure of Al–5Ti–1B master alloy is uniform, fine and no oxide inclusions. The average size of TiAl3 and TiB2 phases is 16.7 and 0.73 µm, respectively. By adding 0.2 wt% Al–5Ti–1B master alloy, the grain size of pure Al has been refined to 75.7 µm, showing an excellent grain refining efficiency, strong ability to anti-fading and good adaption to a wide range of aluminum-melt temperature.
