Production and testing of Al-ferroniobium composites

Abstract

A composite material is called a Metal matrix composite (MMC) when the matrix material is a metal (Al, Mg, Cu,etc.). Reinforced material is chemically distinct which may be particulate, fibers, whiskers form, etc. when reinforced material is added to the matrix metal in proper proportion it increases its mechanical properties. The Aluminum class of matrix material is having large scope for the development of new composite material based on its favorable properties such as high strength on account of weight comparison and low density that it possesses. In this research paper, an effort was made to develop a composite material with ferroniobium (Fe-Nb) as the reinforcement material. As an initial stage of research, large weight portions (10, 20, 30, 40 %wt) of Fe-Nb particulate was added to analyze the mechanical propertiesof the Al6061 MMC. Stir casting methodology was selected considering its low cost of production. The stirring speed was maintained as 200 rpm and stirring time as 15min. It was noticed that with a gradual increase in %wt portions of reinforcement, eventuated increase in mechanical properties. This paper aims at the fabrication of MMCs via. Stir Casting route and characterization of the composite were studied.
