摘要：
A method for inspecting a titanium-based alloy that comprises alpha phase grains to detect flaws in the titanium-based alloy, the titanium-based alloy comprises an alpha phase that is provided by thermomechanically processing the alloy to provide a microstructure which comprises the alpha phase that defines an average grain size and a crystallographic orientation of the grains of the alpha phase that is highly randomized. The method comprises ultrasonically inspecting the titanium-based alloy using an ultrasonic beam, the ultrasonic beam comprising a cross-sectional area that is less than the average grain size of the alpha phase in the titanium-based alloy; and determining flaws based on the step of ultrasonic inspecting.
