Workability Behavior of Powder Metallurgy Carbide Reinforced Aluminum Composites During Hot Forging

Abstract

Experimental study was conducted to assess the consequence of titanium carbide (TiC), molybdenum carbide (Mo₂C), iron carbide (Fe₃C), and tungsten carbide (WC) reinforcements on the composite aluminum compacts. The hot deformation of the carbide reinforce aluminum compacts, Al-2TiC, Al-2WC, Al-2Fe₃C, and Al-2Mo₂C, with aspect ratios of 0.4 and 0.6, was carried out and the workability behaviors of the same were determined. The effect of carbide reinforcement and preform geometry on the relative density, stress ratio, σ_θ/σ_eff, and formability ratio was studied.
