High strength tungsten wire reinforced Zr-based bulk metallic glass matrix composites prepared by continuous infiltration process

Tungsten fiber reinforced Zr41.25Ti13.75Cu12.5Ni10Be22.5 bulk metallic glass matrix composites (BMGMC) were prepared by continuously drawing a bunch of preform from molten alloys. The novel processing makes the interface of composites well combined and the mechanical properties enhanced, e.g., the tensile strength of BMGMC rod with 61.4 vol% tungsten fibers reaches 2867 MPa, which is the highest among this kind of composites. It is found that the strengthening of tungsten is attributed to confinement of the propagation of shear bands.

► Bulk metallic glass matrix composites were prepared by using continuous process.
► Interfaces of composites and the mechanical properties are analysed.
