Experimental investigation has been carried out to evaluate the effect of titanium
carbide (TiC) addition on the composite aluminium preforms. The hot upsetting of the
composite aluminium preforms with varying TiC contents, namely, 1%, 2%, 3% and 4%, and
different aspect ratios, namely, 0.2, 0.4 and 0.6, was carried out and the workability behavior
of the same was determined. The influence of TiC addition, in the aluminium composite, on the
relative density (R), stress ratio parameters, σθ, σeff and
σz/σeff and formability
stress index was studied. The effects of initial preform geometry and initial theoretical density
on the workability behavior have been studied.
Keywords: workability; stress ratio parameter; formability stress index; relative density; triaxial stress. |
