Abstract
The TiB 2 particulate reinforced magnesium matrix composites (MMCs) were fabricated by adding a TiB 2–Al master alloy processed via self-propagating high-temperature synthesis (SHS) reaction of Al–Ti–B systems with the different molar ratio of Ti to B ( n Ti: n B = 1:2 and n Ti: n B = 1:2.5, respectively) to molten magnesium and using the semisolid slurry stirring technique. When the molar ratio of Ti to B is 1:2 in TiB 2–Al master alloy, the TiB 2–Al master alloy and TiB 2p/AZ91 composites contained a certain amount of transient TiAl 3 phase; however, when the molar ratio of Ti to B is 1:2.5, the TiAl 3 phase was almost completely eliminated and the distribution of TiB 2 particulates generally appeared to be more homogeneous throughout the magnesium matrix.
