AbstractMetallic glass composites (MGCs) serve as promising candidates of advanced structural materials. In this work, the Mo element was added to change the dendrite composition of in situ dendrite-reinforced Ti-based MGCs, for exploring the effect of dendrite composition on fatigue behavior. The Mo-containing MGC possessed the lower fatigue lives and fatigue endurance limit, relative to Mo-free MGC. Several characterization methods including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were utilized to reveal the fatigue deformation and damage features. The Mo could change the dendrite stability and then induce the fatigue deformation variation from martensitic transformation and twinning to dislocation slipping. The fatigue crack formed from the metallic glass (MG) matrix phases and deflected when encountering the dendrites in Mo-free MGC; for comparison, the fatigue crack formed from the dendrites and penetrated the adjacent MG matrix and dendrites in Mo-containing MGC. Current results may offer the guidance on future composition design for MGCs with excellent fatigue property.
