摘要：The present invention relates to a process for thermal treatment of a piece ofaluminum alloy casting - pressure comprising the steps of placement in solution of thepart in an oven preheated to a temperature below the solidus of the alloy, of quenchingand annealing of the part of the piece quenched, the step of placement in solution, thepart is maintained at a temperature of the isotherm for a period of at least 10 minutes +rise in temperature is sufficiently fast thanks to a specific furnace, which has a heatexchange coefficient greater than that of a conventional oven at air. The invention makesit possible to obtain mechanical properties for parts made of aluminum alloys are closeto those of other materials such as steel or cast iron.
