Ti-based bulk metallic glass matrix composites with in situ precipitated β-Ti phase fabricated by spark plasma sintering

► Ti-based BMG matrix composites with in situ precipitated β-Ti phase were fabricated by SPS. ► Wider ΔTx and smaller particle size for the as-synthesized amorphous powder are present. ► Spherical nanocrystalline β-Ti is homogeneously precipitated in amorphous matrix. ► The sample sintered at 743 K has high relative density and amorphous phase volume fraction, ► We provide an alternative method for fabricating large-sized BMG matrix composites by SPS.
