Patent number: 9777360Abstract: A method for heat-treating a cast component composed of an aluminum base alloy, in which method the cast component is annealed at a predetermined annealing temperature for a predetermined annealing period in a first heat transfer medium and then transferred into a water bath. Between being annealed and transferred into the water bath, the cast component is transferred into a second heat transfer medium at a predetermined intermediate cooling temperature, where it is held for a predetermined intermediate cooling period.Type: GrantFiled: July 20, 2011Date of Patent: October 3, 2017Assignee: MAGNA BDW Technologies GmbHInventors: Jürgen Wüst, Dirk E. O. Westerheide
