Titanium processing methods for ultrasonic noise reduction

摘要

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 beta-transus temperature; quenching the titanium from a temperature above the beta-transus temperature, the step of quenching titanium forming an alpha-plate microstructure in the titanium; and deforming the quenched titanium into a titanium article, the step of deforming the quenched titanium transforming the alpha-plate microstructure into discontinuous alpha particles without crystallization textures. The discontinuous-randomly textured alpha particles lead to a reduction in ultrasonic noise during ultrasonic inspection.
