Semi-Solid Metalworking (SSM) incorporates elements of both casting and forging for the manufacture of near-net-shape discrete parts. Parts produced by SSM have higher structural integrity, quality and soundness than castings, yet can be produced at lower cost than parts produced by fully-solid processes. In addition, SSM is capable of producing parts which are essentially free of the porosity associated with high pressure die casting. A carefully designed, systematic experimental approach was used to analyze the SSM process. This paper examines billet structure, induction heating variables, die design, die temperature, die lubricant, venting, ram speed and pressure and correlates these with their effect on improvement in part quality.
