چکیده:

Today the development of innovative production technologies has became a major factor in global competition. One of these innovative production technologies in metal forming field is semi-solid forming (SSF). Especially for metals that are difficult to process with conventional technologies, semi-solid metal forming offers the possibility of significant gains in product quality and productivity of the forming process. In current study, one of the most conventional procedures between semi-solid forming processes, i.e. thixo forward extrusion, has been analyzed. In fact this process has been simulated by using the SupperForge software that is based on the finite volume method. As one of the purposed results of simulation, temperature distribution in whole workpiece at different steps of forming process has been studied. Based on simulated process results, temperature distribution can be influenced by different process parameters including on extrusion ratio, die angle and punch velocity.
