| 发明名称 | Methods for forming ceramic reinforced titanium alloys | ||
| 摘要 | In accordance with an exemplary embodiment, a method of forming a ceramic reinforced titanium alloy includes the steps of providing, in a pre-alloy powdered form, a ceramic reinforced titanium alloy composition that is capable of achieving a dispersion-strengthened microstructure, directing a low energy density energy beam at a portion of the alloy composition, and forming a ceramic reinforced titanium alloy metal having ceramic particulates of less than 10 μm on a weight-average basis. The step of forming includes the sub-steps of withdrawing the energy beam from the portion of the powdered alloy composition and cooling the portion of the powdered alloy composition at a rate greater than or equal to about 106° F. per second, thereby forming the ceramic reinforced titanium alloy metal. | ||
