Abstract: A fastening assembly includes a magnesium alloy member, a metallic sheet defining a through hole, a metallic bolt, and a nut positioned on an end of the bolt and attached to the metallic sheet. The magnesium alloy member includes a magnesium alloy base, and at least one resin coating layer formed in at least one portion of the magnesium alloy base. The magnesium alloy member defines a through hole penetrating through the magnesium alloy base and the at least one resin coating layer. The metallic bolt extends through the through holes of the magnesium alloy base and the metallic sheet. An inner width of the through hole of the magnesium alloy member is greater than a width of the metallic bolt, a material of the metallic bolt is different from a material of the magnesium alloy base or a material of the metallic sheet.

Abstract: A method for fabricating a light metal-based nano-composite material, the method includes the steps of: (a) providing melted metal and nanoscale reinforcements; (b) ultrasonically dispersing the nanoscale reinforcements in the melted metal by means of ultrasonically mixing to achieve a mixture with the nanoscale reinforcements uniformly dispersed therein; and (c) cooling the mixture.

Abstract: An exemplary magnesium alloy member superior in corrosion resistance includes a magnesium alloy base, at least one resin coating layer formed in at least one portion of the magnesium alloy base. Methods for making the magnesium alloy member are also provided.

Abstract: An improved casting nozzle for continuous slab casting machines is provided. The nozzle includes a sloped surface which reduces molten metal turbulence during the casting process. The nozzle also includes a resilient, thermal insulation layer which prevents undesired backflow and premature solidification of the molten metal near the nozzle tip. The nozzle may also include a friction reducing layer which prevents excessive wear or fracture of the nozzle as it contacts the casting mold. The casting nozzle is suitable for use with both horizontal and vertical continuous casting machines, and may be used with various types of casting molds including continuous belt or caterpillar molds, and stationary molds. The improved nozzle may be used to cast various metals such as aluminum and aluminum alloys.
