Effect of Modified Aging Treatments on the Tensile Properties, Quality Indices and Fatigue Life of Cast Components of Aluminum Alloy 354

  • Chapter
Light Metals 2014

Abstract

With the drive to build higher performance automobile engines, there has been a steady demand to further improve the mechanical behavior of the cast aluminum alloy 354 through improvements in processing. The present study explores the possibility of improving the tensile properties, quality indices Q & QC and fatigue life of the alloy over those obtained by standard T61 treatment by adopting different modified aging treatments. These include i) lowering the artificial aging temperature ii) interrupted aging cycles similar to T6I4 referred to in the published literature and iii) artificial aging in two steps instead of in single step. Based on the results, a few modified aging treatments could be identified which lead to a comparable combination of tensile properties, but with improved fatigue life and a shade higher quality level.
