Good Agreement

The thixo-forging of magnesium matrix composite was analyzed with computer numerical simulation based on rigid viscoplastic finite element method. The constitutive model of SiCp/AZ61 composite was established in our prior literature. Behavior of metal flow and temperature field were obtained. The differences between traditional forging and thixo-forging processes were analyzed. Results indicated that thixo-forging was better in filling cavity than forging. Simulation results were good agreement with experimental ones.

Semi Solid

The conventional liquid die casting and rheo-diecasting processes of magnesium matrix composites were studied with the numerical simulation method. The constitutive model of semi-solid Mg2Si/AM60 composite had been established in our prior study. The pressure and the inside defects of the material during rheo-diecasting is realized. The comparison of two forming processes is done. The results indicate that the rheo-diecasting won't lead to interior defects such as gas-hole etc. The simulation results are in accord with the experimental ones.

Chemical Plating

Under the protection of argon gas, carbon nanotube reinforced magnesium metal matrix composite was made by stirring carbon nanotube into magnesium melts and formed by die casting. TEM and EDS methods were introduced to analyze boundary structure and chemical composition between carbon nanotube and magnesium metal matrix. The mechanical carbon nanotube properties of the composite were tested. Nickel chemical plating surface of carbon nanotube is favorable to adhesion of carbon nanotube to magnesium. Tests show that carbon nanotube, especially chemical nickel-plated one, has excellent role in strengthening the magnesium. The structure of magnesium was fined .The tensile strength, elongation, hardness and elastic modulus of the composite are improved.
