Abstract

This paper depicts the current processing of aerospace aluminium alloy Al-Li extruded material, with emphasis on nonconformities caused by the permanent fluorescent background during dye penetrant inspection. The process for dye penetrant inspection is described in full details to provide a clear image about each individual processing step. The second part includes a series of tests performed on aluminium alloy Al-Li type material during dye penetrant inspection, as part of the root cause identification process. The last part of the paper illustrates an innovative hypothesis related to the cause behind the permanent fluorescent background during dye penetrant inspection. The innovative hypothesis related to the influence of lithium concentration at the surface of the Al-Li aerospace alloy extrusions is tested by relevant trials and results are presented as part of the conclusions.
