METHOD FOR HEAT-TREATING A CAST COMPONENT

摘要

The invention relates to a method for heat-treating a cast component (10) made from an aluminium base alloy, in which method the cast component (10) is annealed at a predetermined annealing temperature (T1) for a predetermined annealing time (t1) in a first heat-transmission medium (14) and is then transferred to a water bath (20), the cast component (10), between the annealing stage and the transfer to the water bath (20), being transferred to a second heat-transmission medium (16) at a predetermined intermediate cooling temperature (T2) and being held there for a predetermined intermediate cooling period (t3).
