| titleOfInvention | A kind of high-strength plastic high-rigidity aluminum matrix composite material and preparation method |
| abstract | The invention discloses a high-strength, plastic and high-rigidity aluminum-based composite material and a preparation method. It includes the following steps: (1): preparation of the original powder; (2): ball milling: after ball milling, the powder is pressed and formed by a hydraulic press; (3): vacuum sintering: the pressed block is put into a vacuum furnace for sintering to obtain the mass fraction It is a 5%-30% modified Al 3 BC/Al-Mg-Si composite material. The morphology of Al 3 BC particles in the composite material is spherical and has a core-shell structure. The core part is Al 3 BC phase, and the shell part is The TiBC ternary phase composed of Ti, B and C has a size of 50nm-200nm and is uniformly distributed in the matrix; step (4): extrusion deformation. This patent innovatively regulates the morphology and scale of Al 3 BC, so that the morphology is modified from flakes to spherical particles, thereby improving the anisotropy of the composite material, making it isotropic, and realizing the composite material. of high stiffness and high-strength plastic properties. |
