Workability behavior of powder metallurgy aluminum reinforced carbide composites during hot deformation

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 aluminium compacts. The hot deformation of the carbide reinforce aluminium compacts, Al-2TiC, Al-2WC, Al-2Fe3C and Al-2Mo2C, with aspect ratios (AR) of 0.4 and 0.6, was carried out and the workability behavior of the same was determined. The effect of carbide reinforcement and preform geometry on the relative density, stress ratio, σ θ σ eff / , and formability ratio was studied
