? 2021 Elsevier LtdTi-based bulk metallic glass composites (BMGCs) with the microstructure consisting of micro-scale β-Ti dendrites and nano-scale interdendritic glassy matrix were prepared via suction casting. Effects of minor Sn addition on mechanical behavior of the BMGCs were investigated. It was found that the Sn addition presented “dual effects” on mechanical properties of the dendrites in the BMGCs, i.e., solid solution strengthening and increase of Young's modulus. As a result, remarkably enhanced strength without reducing plasticity could be achieved for the BMGCs. The BMGCs exhibited a unique plastic deformation mode, which was attributed to the presence of the glassy matrix in nano-scale. The results might give some hints for improving the mechanical properties of dendrite-reinforced Ti-based BMGCs by tuning the microstructure.
