The invention discloses a
titanium-based amorphous / pure
titanium double-continuous phase
composite material and a preparation method thereof, and belongs to the technical field of
titanium-based amorphous composite materials. The titanium-based amorphous / pure titanium double-continuous phase
composite material comprises a titanium-based amorphous
alloy and a three-dimensional communicated
porous titanium skeleton. The three-dimensional communicated
porous titanium skeleton is filled with the titanium-based amorphous
alloy so that a double-continuous phase structure is formed. The preparation method comprises the following steps of 1, heating to melt the selected titanium-based amorphous
alloy, and 2, filling the three-dimensional communicated
porous titanium skeleton with the liquid titanium-based amorphous alloy by a
percolation method and carrying out water
quenching, or 3, extruding the titanium-based amorphous alloy melt into a
metal mold with a titanium skeleton by an
extrusion casting method so that the titanium-based amorphous / pure titanium double-continuous phase
composite material is obtained. The
amorphous phase and the second phase (pure titanium phase) of the composite material have uniform and continuous distribution structures in the three-dimensional space, and through collaborative deformation, the two phases are mutually reinforced so that the problem of poor titanium-based
amorphous phase plasticity is solved and control of composite material
microstructure uniformity is realized. The titanium-based amorphous / pure titanium double-continuous phase composite material has the characteristics of excellent mechanical properties, high
specific strength, uniform and controllable
microstructure and no defects.
