Theoretical Study of The Alloying Elements on the Properties of Tib2 Ceramic Reinforced Fe Matrix Composite

Abstract

In recent decades, ceramic particles reinforced iron matrix composites (CPRIMCs) are regarded as the main achievements in wear resistant materials area [1-3]. Among many iron matrix composites, TiB2 ceramic reinforced Fe matrix composite (TiB2/ Fe) behaves large elastic modulus, high mechanical strength, and advanced hardness and wear resistance [4,5]. Additionally, the high electrical conductivity of TiB2 ceramic [6] enables machining of TiB2/Fe composite easily using electrical discharge machining. Agarwal and Dahotre [7] discussed the reinforcing mechanism of TiB2/Fe composite, the epitaxial growth of iron on TiB2 particles is revealed, and the orientation relationship was found as TiB2 (0001)/Fe (111). However, much less information is available for the effects of alloying elements on the properties of TiB2/Fe interface.
