    Abstract: A composition of matter is generally provided, in one embodiment, a titanium alloy comprising 5 wt % to 8 wt % aluminum; 2.5 wt % to 5.5 wt % vanadium; 0.1 wt % to 2 wt % of one or more elements selected from the group consisting of iron and molybdenum; 0.01 wt % to 0.2 wt % carbon; up to 0.3 wt % oxygen; silicon and copper; and titanium. A turbine component is also generally provided, in one embodiment, that comprises an article made from a titanium alloy. Additionally, methods are also generally provided for making an alloy component having a beta transus temperature and a titanium silicide solvus temperature.

    Abstract: A method of making a hollow metal component comprising the steps of providing at least one core comprising a first side and a reverse side; utilizing a first metal spray process to apply at least one metal or metal alloy to the first side of the core, resulting in a partially-formed structure comprising a first side and a reverse side; and utilizing a second metal spray process to apply at least one metal or metal alloy to the reverse sides of the partially-formed structure and the core, resulting in a rough structure. A hollow metal component comprising a first side having interior and exterior surfaces, a reverse side having interior and exterior surfaces, the interior surfaces of the first side and the reverse side defining at least one cavity. The component is integrally formed and has regions comprising relatively different material compositions, the regions having gradual transitions of materials therebetween.

    Abstract: Acoustic inspection systems and methods are described herein useful to determining microstructural characteristics, such as microtexture regions (MTRs), of a material sample. In some embodiments, a method of determining a material characteristic of a material sample includes transmitting acoustic waves from transducer having a concave face that includes one or more piezoelectric elements through a coupling medium and to a surface of a material sample to produce surface acoustic waves along a portion of a surface of the material sample. The one or more piezoelectric elements of the concave face may operate as at least one of an acoustic transmitter or an acoustic receiver. The method also includes receiving the surface acoustic waves reflected from the surface of the material sample at the concave face. The method then includes determining at least one material characteristic of the material sample based on a property of the surface acoustic waves.
