Processing and Application of In-Situ Tib2 Reinforced Aluminium Matrix Composites

Abstract

Aluminium matrix composites with TiB₂ reinforcements have several applications in aerospace and automobile industries due to their high specific strength, stiffness, hardness and wear resistance. TiB₂  reinforcements incorporated in the Al matrix via the in situ reaction has the advantage of delivering clean interface between the matrix and the particle, thermodynamic stability and finer distribution of the  second phase particles. Fabrication methods of Al-TiB₂ in situ composites include both liquid state and solid state processing. In this paper we provide the highlights of the development, properties and applications of in-situ Al-TiB₂ metal matrix composites in the industries.
