摘要

近几十年来,陶瓷颗粒增强铁基复合材料(cprimc)被认为是耐磨材料领域的主要成果[1-3]。在众多铁基复合材料中,TiB2陶瓷增强铁基复合材料(TiB2/ Fe)具有弹性模量大、机械强度高、硬度和耐磨性高等特点[4,5]。此外,TiB2陶瓷的高导电性[6]使TiB2/Fe复合材料的电火花加工变得容易。Agarwal和Dahotre[7]讨论了TiB2/Fe复合材料的增强机理,揭示了铁在TiB2颗粒上的外延生长,发现取向关系为TiB2 (0001)/Fe(111)。然而,合金元素对TiB2/Fe界面性能影响的研究却很少。

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