Abstract
The influence of solution heating at 540oC 1-6 hours, quenching into 20oC cool water and ageing at 175oC 2-8 hours in air on transformation of acicular, plate-like and flake-like morphologies to broken grains and gradually form round to globular ones was researched. The microstructural eutectic silicon, a-aluminium, acicular intermetallic phases in high silicon aluminium alloys were examined with confidence microscopy, scanning electron microscopy and X-ray. The results showed that the solution treatment at 540oC 1-2 hour then quenching attained very positive influence on the alloy's tensile strength.
