Abstract

Microstructural evolution and Mechanical properties of in-situ Al5083 composites with 1 and 5 volume percent of TiB2 reinforcement particles were investigated. It was revealed that hot extrusion process results in a uniform, more homogeneous and less clustered structure of TiB2 particles compared with the as-cast structures. Scanning electron microscopy showed that TiB2 particlesin the Al5083-1 vol% TiB2 composite have a nearlyequiaxed morphology and round shape with an average size of ~ 0. 5 μ m. While, the morphology of TiB2 particlesin Al5083-5 vol% TiB2 composite is hexagonal with an average size of ~ 2 μ m. Also, the grain size reduces by adding TiB2 reinforcement particles to the Al5083 alloy. It was shown that the hardness, yield strength, young’ s modulus, and ultimate tensile strength of the Al5083-TiB2 composites increase with increasing TiB2 content. This can be attributed to the effect of TiB2 particles as a high hardness reinforcement phase and also the smaller grain size of the matrix which was resulted by adding the TiB2 particles.
