Production and characterization of Fe3Al nanocomposite reinforced with WC Hesam Atashtar h atashtar@ma iut ac ir March 10th 2013 Department of Materials Engineering Isfahan University of Technology Isfahan 8415683111 Iran Degree M Sc Language Farsi Supervisors Prof Ali Saidi a saidi@cc iut ac ir Prof Mohammad Hasan Abbasi Abbasi32@cc iut ac ir Abstract The aim of this study has been in situe production of iron aluminide and tungsten carbide nanocomposite with mechano chemical thermal synthesis In this regard the possibility of combustion synthesis of activated samples has been investigated Three mixtures of raw materials were used to produce nanocomposites Fe Al WC The first mixture is based on Fe Al C and W powder the second one is based on Ferro tungsten Al and C and the third one is the direct use of WC hours of milling the powder mixture of Al Fe C and W result in Fe Al production but even by hours milling WC was not formed and just lead to increase in lattice strain and decrease in grain size Milling the mixture of ferro tungsten aluminum and carbon up to hours only increase the lattice strain and decrease the grain size and no reaction takes place hours of milling the mixture of Fe Al and WC produces Fe Al In addition XRD tyupical peaks of Fe Al and WC indicate that there is no by product Samples heated at temperatures of and C for minutes combustion reaction was carried out and complex carbides of Fe Al WC were generated These carbides constitute of tiny crystals that have been sintered in the form of clusters Heat treatment of combustion synthesis samples at C for one hour results in WC production and disintegration of the complex carbides Microhardness as high as HV was obtained for the produced composites Keywords Nanocomposite Iron Aluminide Tungsten Carbide Mechano chemical Termal SynthesisPDF created with pdfFactory trial version www pdffactory com
