Aluminum alloy forgingis a processing method that uses a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with mechanical properties, shape and size. One of the two major components of forging (forging and stamping). Through forging, defects such as as-cast looseness produced by the metal during the smelting process can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of Aluminum alloy forging are generally better than those of the same material. For important parts with high load and severe working conditions in related machinery, forgings are mostly used in addition to rolling plates, profiles or welded parts with simple shapes.
Characteristics of aluminum alloy forgings
Compared with castings, the structure and mechanical properties of metals can be improved after forging. After the casting structure is deformed by the forging method, due to the deformation and recrystallization of the metal, the original coarse dendrites and columnar grains become an equiaxed recrystallized structure with finer grains and uniform size, which makes the original segregation and recrystallization in the steel ingot. Porosity, pores, slag inclusions, etc. are compacted and welded, and the organization becomes more compact, which improves the plasticity and mechanical properties of the metal. The mechanical properties of castings are lower than those of forgings of the same material. In addition, the forging process can maintain the continuity of the metal fiber structure, so that the fiber structure of the forging is consistent with the shape of the forging, the metal streamline is complete, and the parts have good mechanical properties and long service life. Precision die forging, cold extrusion, warm Forgings produced by extrusion and other processes are incomparable to castings. Forgings are objects in which metal is pressed and plastically deformed to shape the required shape or suitable compressive force. This force is typically achieved through the use of a hammer or pressure. The casting process builds up the grain structure and improves the physical properties of the metal. In real-world use of the component, a proper design enables particle flow in the direction of the main pressure. Castings are metal forming objects obtained by various casting methods, that is, the smelted liquid metal is injected into the pre-prepared casting mold by pouring, injection, suction or other casting methods, and after cooling, it is subjected to falling sand, cleaning and post-processing. Processing, etc., the resulting article of shape, size and properties.
