Exploration of Al Matrix Composites Reinforced with Al-Ti Intermetallics/Ti Metal Compound Spherical Agents
In this paper, Al matrix composites reinforced with Al-Ti intermetallics/Ti metal compound spherical agents were successfully fabricated through powder metallurgy way. Al-Ti intermetallic including Al3Ti and TiAl phases are main reinforcements and inner Ti metal could not only play reinforce role but also reduce the crack sensitivity of Al-Ti intermetallics. This kind of reinforcements bonded strongly with Al matrix. As expected, the resultant composites exhibit promising mechanical properties at ambient temperature. And the mechanical property could be improved through regulating the relative thickness of the Al-Ti intermetallics and Ti metal layers.
