| Abstract: |
| Titanium-aluminum alloys are prone to cracks and oxidative inclusions when prepared by the thermal processing-type additive manufacturing technologies. With solid-phase additive manufacturing, the problems of cold spraying (CS) direct deposition of titanium-aluminum intermetallic compounds can be solved, but the metal particles are hard and brittle, resulting in a very low deposition rate or deposition failure, etc. In response to the needs of additive manufacturing of titanium-aluminum alloys, the combination of cold spraying and friction stir processing (FSP) method for the in-situ preparation of the titanium-aluminum is adopted. In order to meet the demand for additive manufacturing of titanium-aluminum alloys, the alloys are prepared in situ by combining cold spraying and friction stir processing. |
