摘要：

Aluminum alloy A356-TiB2 in-situ MMCs have been fabricated by using K2TiF6 and KBF4 at different pouring temperatures, cast with permanent and sand mould conditions. In this present study mechanical properties (i.e.,) Tensile and Hardness properties were studied. The observation of SEM micrographs shows particle distribution of the TiB2 and it appears in hexagonal shape in Al matrix. The results of X-ray Diffraction (XRD) analysis confirmed the formation of those TiB2 particulates and the results showed TiB2 particles are homogeneously dispersed throughout the matrix metal. The hardness and tensile strength of the composites are higher in cast made in permanent mould and the best processing temperature in this study seems to be 820 °C.
