Abstract

The present disclosure provides an amorphous alloy camera frame structure, which relates to the technical field of amorphous alloys. The amorphous alloy camera frame structure comprises a lifting handle and a fixing sleeve plate, the lifting handle being mounted and fixed in a middle position of an upper end of the fixing sleeve plate. In the amorphous alloy camera frame structure provided by the present disclosure, an elastic support plate is welded and fixed to the lower inner sides of a front-side amorphous alloy frame and a rear-side amorphous alloy frame, such that the sizes of the lower inner sides of the front-side amorphous alloy frame and the rear-side amorphous alloy frame can be changed. Two telescopic plates having rolling balls are respectively fixed to the left side and the right side of the fixing sleeve plate and are thus effectively welded and fixed to the front-side amorphous alloy frame and the rear-side amorphous alloy frame. Therefore, during an adjustment, a top gap between the front-side amorphous alloy frame and the rear-side amorphous alloy frame is effectively changed. Since an arc-shaped supporting plate of an elastic holding plate is welded to the lifting handle, the arc-shaped supporting plate and the lifting handle enclose to form a groove area, thereby preventing the handle from sliding and dropping off when gripped.

Abstract

A flame-resistant magnesium alloy and a preparation method therefor, relating to the fields of magnesium based alloys and alloying. According to the magnesium alloy, a certain quantity of calcium and yttrium are added by using a smelting metallurgy method on the basis of die casting of the magnesium alloy. The preparation method for the magnesium alloy comprises: preparation of materials, preheating, feeding, smelting, refining and slag removal, slagging and die casting. While excellent die casting manufacturability and low cost of a die cast magnesium alloy are maintained, an ignition point of the die cast magnesium alloy can be remarkably increased, and high-temperature oxidation resistance of the magnesium alloy is improved, so that the flame resistance is improved, and an application range of the magnesium alloy is further expanded.

Abstract

A method for forming an amorphous alloy member. In the method, within a temperature range from the liquidus temperature to the glass transition temperature in the solidification process of a molten amorphous alloy, low-pressure precision forming is carried out for the amorphous alloy. The method makes use of a smooth, free surface formed after the molten alloy solidifies, good deformation property and low shrinkage coefficient during solidification, to obtain an amorphous alloy member that has high dimensional precision, high surface smoothness and a compact structure without defects such as shrinkage cavities and shrinkage porosity. The method features a short technological process, high production efficiency, and reduced costs.

Abstract

A method for combining amorphous alloy members (10) and a nonmetal member (20), and a product thereof. The method comprises: arranging two or more amorphous alloy members (10) on the periphery of the nonmetal member (20), heating the amorphous alloy members (10) and pressurizing the amorphous alloy members (10) to make corresponding or contact parts of the adjacent amorphous alloy members (10) fused together, wherein the heating temperature for the amorphous alloy members (10) ranges between the glass transition temperature and crystallization temperature of the amorphous alloy members (10). According to the method, because an amorphous alloy is characterized by superplasticity in a supercooled liquid phase region, at the temperature of the supercooled liquid phase region, that is, at the temperature ranging between the glass transition temperature and crystallization temperature of the amorphous alloy, the amorphous alloy is softened and deformed by pressurization, and accordingly, preset nonmetal materials are wrapped by the amorphous alloy or are combined with the amorphous alloy in other manners, and the combination performance is stable; in addition, the method has low requirement for equipment and processes, the cost is low, the obtained product can meet the utilization requirement without subsequent complex machining, and the method is suitable for batch production.
