چکیده انگلیسی
Anisotropic mechanical properties of a Zr-based amorphous alloy matrix composite reinforced with tantalum continuous fiber fabricated by liquid pressing process were investigated by tensile and compressive tests of 0°(longitudinal)-, 45°-, and 90°(transverse)-orientation specimens. The ductility was dramatically improved over that of the monolithic amorphous alloy under tensile compressive loading conditions, while maintaining high strength. When the fiber direction was not matched with the loading direction, the reduction of the strength and ductility was not serious because of excellent fiber/matrix interfacial strength. The anisotropic deformation and fracture analyses showed that the formation of multiple shear bands, obstruction of crack propagation by fibers, and deformation of fibers led to the tensile elongation of 3-4% and compressive elongation of 15-30%. These findings suggested that the liquid pressing process was useful for the development of amorphous matrix composites with excellent ductility and anisotropic mechanical properties.
