- Abstract
- An STS304-continuous-fiber-reinforced Zr-based amorphous alloy matrix composite with excellent fiber/matrix interfaces was fabricated Without pores and misinfiltration by liquid pressing process. Approximately 60 Vol pct of continuous fibers were homogeneously distributed in the matrix, in which considerable amounts of polygonal and dendritic crystalline phases were formed by the diffusion of metallic elements from the fibers. The ductility of the composite under compressive or tensile loading was drastically improved over that of the monolithic amorphous alloy. According to the compressive test results, a strength of 700 to 830 MPa was sustained until reaching a strain of 40 pct, because fibers interrupted the propagation of shear bands initiated in the matrix and took over a considerable amount of load. Under tensile loading, the deformation and fracture Occurred by crack formation and opening at matrices, necking of fibers, fiber/rnatrix interfacial separation, and cup-and-cone-type fracture of fibers, thereby resulting in a high tensile elongation of 27 pct.
