Abstract
Al-5Si and Al-4Mg alloys were spike forged using different lubricants at various temperatures. The effect of friction on material flow and die filling is studied. Split grided samples were also spike forged to study the strain distribution which illustrates the material flow and severity of deformation. Visio-plastic technique was used to evaluate the strain variation and the results are presented in the form of iso-strain contours. It is found that friction has a more dominant role to play than flow stress in controlling the material flow in this type of forging operation and higher friction facilitates better die filling inspite of the higher forming forces encountered.
