Description

[0001] Technical field: [0002] The invention belongs to the field of composite materials, and relates to a bulk amorphous composite material, specifically, an aluminum-based bulk amorphous alloy composite material composed of an amorphous matrix and an endogenous crystal phase, with aluminum element as the main component . technical background: [0003] Aluminum-based amorphous alloy not only has excellent corrosion resistance, wear resistance, chemical properties, etc., but also has very excellent mechanical properties, and its fracture strength is 2-3 times that of traditional aluminum alloys. Traditional aluminum alloys such as AA6061, AA7075, etc., after being strengthened by conventional means, the final room temperature tensile fracture strength can only reach 500-600 MPa, while for aluminum amorphous alloys, the fracture strength can reach about 1200 MPa, far It surpasses traditional aluminum alloys, and it is especially worth mentioning that for composite structur...
