  • Titanium processing methods for ultrasonic noise reduction
    Patent number: 6387197
    Abstract: A method is set forth for processing titanium and titanium alloys into titanium articles, in which the titanium exhibits enhanced ultrasonic inspection results for determining its acceptability in microstructurally sensitive titanium applications. The method for processing titanium comprises providing titanium at a temperature above its &bgr;-transus temperature; quenching the titanium from a temperature above the &bgr;-transus temperature, the step of quenching titanium forming an &agr;-plate microstructure in the titanium; and deforming the quenched titanium into a titanium article, the step of deforming the quenched titanium transforming the &agr;-plate microstructure into discontinuous &agr; particles without crystallization textures. The discontinuous-randomly textured &agr; particles lead to a reduction in ultrasonic noise during ultrasonic inspection.
