Micro-nano dual-scale particle reinforced titanium-based composite material and preparation method thereof

The invention discloses a micro-nano dual-scale particle reinforced titanium-based composite material and a preparation method thereof.The preparation method comprises the steps that a micro-nano dual-scale particle reinforced titanium-based composite material cast ingot is obtained through smelting, the cut micro-nano dual-scale particle reinforced titanium-based composite material cast ingot is subjected to solid solution heat treatment, the solid solution temperature is 1150 DEG C, and the solid solution time is 30 min; carrying out water quenching on the solid-solution-state micro-nano dual-scale particle reinforced titanium-based composite ingot, and cooling a sample to room temperature; and finally, aging heat treatment is conducted for 5 h at the temperature of 800 DEG C, air cooling is conducted to the room temperature after aging, and finally the micro-nano double-scale particle reinforced titanium-based composite material is obtained. Compared with the prior art, the method has the advantages that t
