Abstract

DEVELOPMENT AND TESTING OF WC-FeAl COMPOSITE BY STIR CASTING METHOD

*Rahul Verma

ABSTRACT

Aluminium based MMCs are one of the most useful materials due to their high specific strength, low density and stiffness and increased fatigue resistance which make them suitable for various wear and structural applications in various sector such as aerospace industry, automobile industry, medical sector, sports etc. In the aerospace sector, automobile sector the material used for parts of aircraft, satellites automotive vehicles need high temperature stability, high strength, low density, thus to fulfil the requirement of this it is important to develop a new product which can fulfil all these requirement. Present research work on to develop a new material composite that fulfil all this need. In the present work, an attempt has been made to study the effect of addition of WC as reinforcement in FeAl metal matrix composites which decrease the tensile strength of material.FeAl inter metallic compound has a low density, high melting point and good oxidation and corrosion resistance and high hardness, Here, in the present research work WC – 0, 1,2, 3wt % FeAl composites will be developed by stir casting route and their properties will be examined. The relative density of the various sintered composites will be determined by the Archimedes? principle. The tensile and compressive strength of the composite are determine by using of Universal testing machine. The impact strength of the composite are determine by using of impact and Charpy test. The hardness of the composites was determined using a Vickers micro hardness tester, Brinell harness testing and Rockwell hardness testing machine and the wear strength of the composite are examined by pin on disk wear tester. It was found that both the hardness and the wear resistance of the various WC-FeAl sintered composites increased with the increase in FeAl content.
