X‐ray Microtomographic Characterisation of Porosity and its Influence on Fatigue Crack Growth
Source abstract
Abstract
Cast Al alloys are seeing increasing use in transport applications due to their high strength‐to‐weight ratio at an acceptable cost compared to many ferrous alloys. Therefore, a quantitative characterisation of the pore distribution and its influence on the evolution of fatigue damage are required to predict the fatigue life of cast Al alloy components. In this investigation, X‐ray microtomography was used to characterise the 3D morphology of porosity in A356‐T6 specimens and to relate the porosity to fatigue behaviour.
