In creep-ageforming a material experiences continuously variable bending stressesthrough its thickness, from tensile to compressive, which are maximum at the surfaces. This canpotentially result in through thickness microstructural gradients, due to interactions between thebending stresses, creep, and precipitation occurring during ageing, that can alter a component’sperformance. The aim of the work reported here was to develop an understanding of these effects inan industrial creep ageforming process. For this purpose two aerospace alloys, 7475 and 2022, wereageformed by Airbus UK using industrial scale ageforming tools. Their microstructures wereanalysed in detail by TEM, and SAXS, which revealed significant through thickness microstructuralchanges after forming
