In Situ Fabrication and Microstucture of ZrB2 Particles Reinforced Aluminum Matrix Composites
Abstract：Aluminum matrx composites reinforced by in situ ZrB2 particles are fabricated from A356-AlB-K2ZrF6 system via in-situ melt reaction method, and the morphologies, sizes and distributions of the in situ particles as well as the microstructures, mechanical mechanisms of the composites are investigated by XRD,SEM,TEM and tensile tests. The results indicate that the morphologies of the in situ particles are mainly with ball-shape, the sizes are in nanometer scale and the distributions in the matrix are uniform. The interfaces between the in situ particles and the aluminum matrix are net and no interfacial outgrowth is observed.
