Example Embodiment
[0021] This application uses powder mixing, sintering, and forging methods to prepare Ti 6 Al 4 V high-strength dual-phase reinforced composite material, the present invention will be further described with examples below.
[0022] 1. Mixed powder
[0023] Take 2484g titanium powder of -250 mesh titanium powder, 276g of -250 mesh 60# aluminum vanadium alloy powder, 90g of -250 mesh titanium carbide powder, 150g of -250 mesh titanium diboride powder, and put them into the mixer for mechanical mixing for 1.5 hours. Obtain uniform Ti6Al4V / (3wt%TiC+5wt%TiB 2 ) Composite material mixed powder.
[0024] 2. Suppress
[0025] The mixed powder is put into the mold, and the pressure is maintained for 15 minutes under a pressure of 300 MPa on a mechanical press, and the material is pressed into a round rod of Φ80×150mm. At this time, the density of the material after pressing is 3.75g / cm 3 , Which is 83.5% of theoretical density.
[0026] 3. Sintering
[0027] Put the crushed bar into a vacu...
