Formatted abstract

Aluminium casting alloy 601 has been cast using low pouring temperatures and chemical grain refiner additions, before being partially remelted and quenched. This allowed for the characterisation of the microstructure in the semisolid state, which is the critical microstructure for semisolid metal forming processes.

It has been found that low casting temperature, even without grain refiner additions, can give a microstructure suitable for semisolid metal forming; a microstructure which is fine and non-dendritic.

While castings were never totally non-dendritic in the as-cast condition, it was observed that dendrite fragmentation in the castings poured at low temperatures eliminated this problem given sufficient time.
