ABSTRACT:
The invention concerns a new process for quenching metallic pieces and intended to limit the stresses engendered by quenching without essentially affecting the characteristics.
This process consists of quenching the pieces by immersion in a binder of the clay type suspended in water and with a mineral component such as magnetite, ferrosilicon, baryte. Products to inhibit corrosion, antifoam, or antiflocculant agents can be added to this suspension.
The invention is applied to metallic pieces, but particularly to high resistance aluminum alloy pieces which are made subject to faults caused by the stresses of excessive quenching because of their form or their dimensions.
