Thixoforging, one variant of semi-solid metal processing in which the metallic alloys are processed at low liquid fraction (0.1< Fl < 0.3), is used to produce complex parts with high mechanical properties. Steel thixoforging faces more challenges as compared to that of low melting point materials due to high processing temperature and lack of understanding of the thermomechanical behavior of ma...
Semi-solid forming processes are now used for producing near net shape parts especially in the automotive and aircraft industries. Non Newtonian rheology of semisolid alloys and its dependence on the various parameters such as reheating cycle, method used to produce non-dendritic structure, thermo-shear history etc. have made the simulation of the flow behavior of semisolid material a difficult...
The distribution of liquid at the semi solid state is one of the most important parameters for steel thixoforging. It has a great influence on the viscosity of the material, on the flows and finally on the final shape and mechanical properties of the thixoforged parts. Both ex situ and in situ 3D X-ray microtomography characterizations have been carried out to determine the quantity and localiz...
