【Abstract】 Bulk amorphous composites are a kind of structural material with excellent mechanical properties, which overcome the room-temperature brittleness of amorphous alloy and retain high strength. The investigation of superplastic deformation behavior in the supercooled liquid region can not only guide the establishment, development and perfection of theoretical model, but also accelerate the engineering application of materials.The research status on superplastic forming of bulk amorphous alloys as well as its composites were briefly introduced, focusing on the superplastic rheological behavior of bulk amorphous composites in the supercooled liquid region, microstructure evolution and variation of mechanical properties during superplastic deformation. Finally, some technical problems to be solved in superplastic forming of amorphous composites were put forward.更多还原
