Notes:
In the process of metal plastic forming severe plastic deformations occur to the workpiece.As a result the constitutive relations between material and geometry are nonlinear. One of the mostcommon tools to solve such problems is the finite element method. In thixoforming processes ofsemi-solid metal many factors affect thixoforming fluidity. Therefore it is important to simplify theproblem and predict the metal flow properties. For that reason the thixoforming process of semi-solidAZ91D magnesium alloy was modeled with the theory of rigid viscoplastic finite element methodusing the commercial finite element software DEFORM-3DTM. The fluid and effective stress-strainfields in the thixoforming process were obtained and the relationships among stress, strain rate andtemperature were analyzed
