Analysis of Hot Working Characteristics of Aluminium based composites using Response surface Methodology

During deformation process, it is essential to control the formability parameters viz., stress, strain, temperature, aspect ratio, volume fraction etc., to obtain sound and defect free products. Moreover, in deformation process in general, upsetting in particular, conducting too many trail experiments results in increased experimental time and cost. Hence modeling of process parameter attracts attention of researchers. The objective of modeling the process parameters is to determine which variables are most influential during metal forming operations. In the present investigation, by connecting the influential process parameters during metal forming in general upsetting in particular, a mathematical model have been developed using Design of Experiments (D.O.E) which could be applied to estimate the flow stress. Aluminium MMCs with silicon carbide (SiCp) and aluminium oxide (Al2O3) as reinforcement have been chosen in this current study as it has significant advantage over conventional materials.
