Differential Scanning Calorimetry (DSC) tests were performed on the cast and solutionized 2219Al alloy at varying heating rates, to identify the endothermic peaks corresponding to the precipitation reaction. A new computational model was proposed to evaluate the kinetic parameters, activation energy and subsequently the kinetic rate equation was generated in order to investigate the intensity of precipitation hardening for these alloys.
