Abstract

The purpose of this investigation is to analyze the effect of particle size on the product characteristics of nickel aluminide composites manufactured through combustion synthesis. Four sample combinations, 50 nm aluminum and 100 nm nickel, 50 nm aluminum and 10 μm nickel, 7 μm aluminum and 100 nm nickel and 7 μm aluminum and 10 μm nickel, were generated based on initial particle sizes. Difference in particle sizes of reactants and products are quantified through statistical analysis. Residual stresses exhibited by the inter-metallic prior and after the reaction were assessed and quantified through multiple exposure technique practiced with x-ray diffraction.
