Purpose: The aim is to review creep age forming theoretical fundaments as well as some of our experimental results. Design/methodology/approach: The approach consists of a brief review from basic theoretical concepts of creep and ageing processesincluding a description of anumeric closed form technique to predicting springback in creep age forming. Finally, a work flow to develop a creep age forming process and its respective experimental implementationare shown. Findings: The analytical model and workflow enabled an excellent result of springback predicted value (less than 1%).Research limitations/implications: The experiments only tested simple parts. An improved model is necessary for more complex parts. Practical implications: This work permits to study the creep age forming viability of a given process planning. Originality/value: This review summarizes the main concepts of the creep age forming process and illustrates them by the application of an analytic and numerical modelling performed as a didactic experiment.
