extension of application of magnesium alloys in the more demanding components requires major development in processing technologies. It is well known that the semi-solid metal(SSM) processing...-dendritic microstructure evolution of as-cast alloys generally experienced four stages during semi-solid isothermal heat treatment, that is, the initial coarsening, separation, spheroidization and final......
Hydraulic schematic 4.2 Results of experiments and analysis Fig.14 shows the workpiece from the experiment. The semi-solid billets made by SIMA were heated at 590 ?C for 50 min, then were put into the die and formed under the different pressures of side urn. The pressures of side urn were 46, 34 and 22 MPa, respectively. Fig.14 Workpiece formed by semi-solid thixoforging Fig.15......
