Morphology of silicon grain boundaries in Sr-modified AI-Si eutectic alloys by HREM

Crystallographic changes m the ~'3(110)/{111}, ~f3(110)/{112} and .~9(110)/{112} boundaries reduced by the presence of strontmm m the slhcon phase of St-modified A1-SI alloys have been studied by high-resolution electron microscopy The 2'3 boundaries possessing {111} and {112} planes m the pure silicon phase often exhibit asymmetric morphologies m the Sr-modlfled phase Interaction of various 23...

Mechanical Behaviour of Commercial Aluminium Wrought Alloys at Low Temperatures

Metallurgical Parameters Controlling the Eutectic Silicon Charateristics in Be-Treated Al-Si-Mg Alloys

The present work was carried out on Al-7%Si-0.4%Mg-X alloy (where X = Mg, Fe, Sr or Be), where the effect of solidification rate on the eutectic silicon characteristics was investigated. Two solidification rates corresponding to dendrite arm spacings (DAS) of 24 and 65 μm were employed. Samples with 24 μm DAS were solution heat-treated at 540 °C for 5 and 12 h prior to quenching in warm water a...
