Thermodynamic evaluation of the thixoformability of Al-Si alloys

Thixoforming or Rheocasting must be avoided at temperatures at which the common secondary phase, i.e., usually the eutectc phase present in SSM raw materials, undergoes transformation as this transformation is more complex and less stable than the corresponding one for the primary phase. This simplification increases the number of thixoformable alloys by focusing on the control of SSM processing.
