Deformation field evolution and shear banding of an <italic>in-situ</italic> crystal reinforced amorphous alloy composite

Effect of infiltrating time on interfacial reaction and properties of tungsten particles reinforced Zr-based bulk metallic glass composites

“…On the contrary, the tiny nano-crystals have a pinning effect on the interface which can improve the interface strength [24,19] , and the polygonal crystals can serve as an endogenous reinforcement phase in the composites. Both of them can also hinder the propagation of shear bands during the deformation process of the samples, thus improving the mechanical properties of the composite materials [18] .…”

“…This indicates that W element does not diffuse into the interior of the matrix during the preparation process, but participates in the interfacial reaction with the elements in the matrix at the interfaces to form tiny crystals growing therein. According to References [16][17][18][19], it is contemplated that with the extension of the infiltrating time, the interfacial reaction products of W 5 Zr 3 and CuTi 3 gradually appear near the interfaces, and within the matrix, the crystallization reaction is induced to generate the intermetallic compounds of Zr 2 Cu and CuTi 3 . Figure 4 shows the compressive stress-strain curves of the three tungsten particles reinforced Zr-based amorphous composite materials with different infiltrating times during the compression tests at room temperature.…”
