Abstract (en)
[origin: WO0123633A2] The invention relates to a method for the heat treatment of structure castings from an aluminium alloy. The inventive method comprises the steps: laying the structure casting onto a product receiving device that embraces the contours of said casting, heating up to 490 DEG C in approximately 30 minutes, maintaining the temperature of 490 DEG C for between 90 and 120 minutes, chilling in air from 490 DEG C to approximately 100 DEG C for approximately 4 minutes and optionally and subsequently chilling in water, heating up to 250 DEG C in approximately 15 minutes, maintaining the temperature of 250 DEG C for between 30 and 120 minutes, chilling in air to 40 DEG C and optionally and subsequently chilling in water. The invention also relates to a light-metal alloy for the use in said method. Said alloy has the following composition: Si: 2-11.5 %, Fe: 0.15-0.4 %, Mg: 0.3-5.5 %, Cu: <0.02 %, Mn: 0.4-0.8 %, Ti: 0.1-0.2 %, the rest being aluminium and trace elements, whereby the alloys having a high content of silicon are provided with low contents of magnesium and vice versa.
