Tool Pin

Friction stir processes (FSP) are important for enhancing mechanical properties of metal sheets, such as the tensile strength, the elongation, etc. The stress distribution of the tool pin is affected by the thermo-mechanical characteristics of the workpiece in FSP. Recently, magnesium alloy AZ31 is widely used in machine industries due to the light-weight material property. In this paper, a thermo-mechanical model for FSP using three dimensional FEM analyses is proposed for exploring temperature distributions, strain distributions and stress distributions of the workpiece. The heat generated from the plastic deformation and the friction between the head tool and workpiece is considered as the heat source in the simulation of the FSP process. A commercial finite element code – DEFORM 3D is used to carry out the simulation of the plastic deformation of AZ31 sheets during the FSP. The analytical results of temperature, strain and stress distributions of the workpiece and head tool can provide useful knowledge for tool pin design in FSP

Magnesium Alloy Am60

In this study, the hexachloroethane (C2Cl6) as a refiner was introduced into a cylindrical squeeze casting of magnesium alloy AM60 with a diameter of 100 mm and a thickness of 25 mm. The casting was prepared under an applied pressure of 30 MPa. The results of tensile testing indicate the tensile properties for the C2Cl6-refined specimens were significantly improved over the untreated AM60 samples. Microstructure analyses with optical microscopes reveal the great grain refining capability of C2Cl6 on squeeze cast magnesium alloy AM60, which should be responsible for the enhanced tensile properties of the refined AM60.
