In his long and illustrious career at the University of Michigan, Prof. J Wayne Jones also pioneered the methods for relating the fatigue life of cast aluminum alloys to their porosity distribution. In the present work, application of a similar methodology to predict the 350oC high cycle fatigue life of an additively manufactured Al-Ce-Ni-Mn alloy will be discussed. It will be demonstrated that with well controlled additive processing schemes, the likely crack initiating features including porosity are considerably refined. Impurities such as oxide particles become crack initiation sites and a model incorporating the effect of the size and distribution of these oxides on the fatigue life will be presented. Based on the results, the authors will make a case for the considerable promise of additively manufactured aluminum alloys for elevated temperature applications.
