摘要：

7010 Al alloys with and without scandium addition were processed in the form of plates and subsequently heat treated to the peak aged temper. The fatigue initiation thresholds, fatigue propagation threshold, and the Paris constants of these alloys were evaluated. The investigations revealed that the scandium addition refines the grain structure but results in poor fatigue crack growth resistance and fatigue thresholds. (C) 2004 Acta Materialia Inc.
