| titleOfInvention | Powder metallurgy densification pressureless sintering method of Ti-Al alloy |
| abstract | The invention belongs to the technical field of alloys, and particularly relates to a powder metallurgy densification pressureless sintering method of a Ti-Al alloy. The invention provides a powder metallurgy densification pressureless sintering method of Ti-Al series alloy, which adopts a temperature programming mode to carry out pressureless sintering, and adopts different protective atmospheres and gas flow rates at different temperature rising stages of sintering to obtain the Ti-Al series alloy with higher compactness. The embodiment result shows that the density of the Ti-Al alloy prepared by the invention is up to more than 98 percent; the quasi-static compressive strength reaches more than 1100MPa, and the critical failure strain exceeds 0.4. In addition, the powder metallurgy pressureless sintering method provided by the invention has low production cost and can realize the mass production of Ti-Al alloy special-shaped pieces. |
