Three-Dimensional Analysis of Microstructure in Cast Aluminium Piston Alloys

  • Conference paper

Abstract

The 3D architecture of intermetallics distribution in two model cast aluminium piston alloys is examined using synchrotron X-ray microtomography and advanced image analysis tools. The highly complex morphology and 3D interconnectivity of intermetallics is delineated using advanced 3D image analysis tools. A novel technique which circumvents quantification difficulties associated with the high interconnectivity is employed for quantifying intermetallic particles. The intermetallic particle size distribution is then analysed using extreme value statistics to predict the maximum particle size in a sample of S-N fatigue specimens and subsequently, the lower bound fatigue life in the given sample.
