Description
Technical Field
The invention belongs to the technical field of metal material rolling, and particularly relates to a current auxiliary phase-controlled aluminum alloy/amorphous alloy rolling composite process.
Background
The amorphous alloy (iron-based amorphous alloy, nickel-based amorphous alloy or zirconium-based amorphous alloy) has many unique properties, such as excellent magnetism, corrosion resistance, wear resistance, high strength, hardness and toughness, high resistivity and the like, and has important strategic application value in many high and new technical fields. However, the plastic deformation mechanism of the amorphous alloy is completely different from that of crystalline metals, the amorphous alloy is usually poor in plasticity at room temperature and difficult to form and compound, and atoms in the amorphous alloy are arranged in disorder and have no lattice defects such as dislocation and the like, so that the localized deformation in the amorphous alloy is difficult to slip like dislocation, the room-temperature deformation of the amorphous alloy is mainly concentrated in a localized shear band, the problem of fragmentation is easy to occur in the rolling process, and the further development of the amorphous alloy is influenced.
At present, the free volume content and distribution form in the amorphous alloy are regulated and controlled by prefabricating a shear band in modes of shot blasting, cold rolling and the like, or rapidly annealing, cold and hot circulation and the like, so that the room temperature plasticity of the amorphous alloy can be enhanced to a certain degree. However, the plasticizing amplitude is limited, so that the room-temperature forming performance of the amorphous alloy cannot meet the requirements effectively, and therefore, the amorphous alloy needs to be compounded with other metals with high specific strength and good plasticity in a rolling compounding manner, so that the advantages of the amorphous alloy are fully exerted.
Amorphous alloy thermoplastic forming can generally achieve greater material deformation and processing efficiency than room temperature plastic forming. During the continuous heating process, the amorphous alloy can be transformed into viscous supercooled liquid state in a certain temperature range far below the melting point of the amorphous alloy. The super-cooled liquid state can keep a specific shape and has lower viscosity, and the amorphous alloy can realize thermoplastic forming like a thermoplastic high polymer material in the state.
The amorphous alloy has superplasticity in a supercooled liquid region, namely between the glass transition temperature and the crystallization temperature, but the temperature range of the supercooled liquid region is influenced by the heating rate, and the wide thermoplastic forming region can be obtained by quickly heating, so that the quick heating and the accurate temperature control are key factors for promoting the amorphous alloy plastic forming, and the application of the amorphous alloy plastic forming in rolling can be promoted by realizing the temperature control and the phase control of the amorphous alloy through current regulation.
