Abstract

Cold upsetting experiments under unlubricated conditions were carried out on as cast and homogenized AA2014/SiC/10p composite billets having dispersoids in size range of 20–40 lm. The study was aimed to evaluate the effect of homogenization on their deformation behaviour. Optical and scanning electron micrographic examination of the samples was also undertaken. Hardness measurements were carried out to observe changes, if any, before and after the forging. Ring compression tests were also carried out to determine the coefficient of friction between the platens and the work piece, which is a necessary requirement to carry out simulation studies. FEM simulation analysis of the forging of composite cylinders was then undertaken using MSC-Marc software with a specified diameter-to-height ratio. Detailed comparisons of the experimental variables with the finite element method (FEM) results were carried out to ascertain the accuracy with which the deformation process can be modelled. Predictions from the simulation results were found to be in good agreement with the actual experimentation.
