Abstract

The application discloses a kind of aluminum matrix composite radial forging methods, belong to metal material processing field.The aluminum matrix composite blank is placed in heating furnace, with furnace temperature rises to 350~500 DEG C and is kept for 6~16 hours, blank is transferred to radial forging machine and is carried out radial forging, blank is turned over, and the blank is forged, immediately aluminum matrix composite blank is transferred to 350~500 DEG C heating furnace and is kept for 6~16 hours, repeat step S2 and S3, until blank is forged to the diameter size required.The application adopts the radial forging method of small deformation multiple deformation, realizes similar extrusion effect, the accurate control of blank diameter and the uniform distribution of deformation and microstructure in the radial direction of blank, effectively improves the uniformity of structure and product performance stability, and can realize high-quality, high productivity and low cost preparation of aluminum matrix composite rod for aluminum matrix composite.
