Abstract

The solidification microstructures formed in a model 6082 alloy with 0.2–1.0 wt % Fe were examined under different cooling rates and the effects of 0.5 wt % Mn and Al–5Ti–1B grain refiner addition investigated. The results were compared against Thermo-Calc, differential scanning calorimetry (DSC) an...
