III. NUMERICAL SIMULATION An attempt is made to simulate the semisolid metal process using finite element simulation software. The following simulations were carried out on Aluminum alloy A356 to determine the effect of initial temperature of the billet on the forging load. The simulations were carried out at different temperatures between the solidus and liquidus temperature range of the alloy. The position of the billet on the bottom die was determined by placing it in different positions and
