The task of the research is to study the processings of manufacturing thixotropic slurry of the ZL112Y aluminum alloy in continuous semi-solid thixoforming , design a set of logical continuous remelting equipment and look for a set of reasonable heating parameters in continuous remelting processing.

To optimize the process parameters for preparing AZ31 Mg-alloy by continuous rheo-extrusion,the temperature and velocity fields at different casting temperatures were modeled by FEM simulation of which the results were verified through some tests to discuss the effect of thermal-fluid coupled field on the microstructure of AZ31 alloy.

The comparisons of the advantages and disadvantages between the different forming techniques were made and the differences and features of the die forming and the flexible forming as well as the sectional forming and the continuous forming.

, the continuous and the discontinuous deformation analysis methods.

The research status in quo and the last evolution of all these numerical methods are summarized through dividing them into two classes,that is,the continuous and the discontinuous deformation analysis methods.

Recognition of 2-dimensional continuous deformation image;

In this paper, we adopt a skill of remeshing procedure and an idea in classification of continuous deformation into those with and without preserving topological structures, and introduction of a new method for identifying continuous deformation.
