Description:: Dilute Al-Sc-Zr-Si-based aluminum alloys retain their strength for long periods of time at elevated temperatures due to a dispersion of nanometric, coherent, and coarsening-resistant Al3(Sc,Zr) (L12 structure) nanoprecipitates that are formed upon aging. These alloys are attractive for replacement of dense steels and costly Ti alloys in the 250–400 °C...
