| Abstract: | Several indices are available in the literature to assess the structural quality of cast Al alloys, especially Al-7 pct Si-Mg
alloys that are based on tensile test results. Some of these indices, most notably the one developed by Drouzy et al., provide a number that necessarily does not have a physical meaning, whereas the others are a measure of what fraction of
the expected tensile performance is achieved. These indices are analyzed in depth, their similarities and shortcomings are
discussed in detail, and recommendations are made. |
