ALUMINIUM ALLOY CONTAINING MAGNESIUM AND SILICON. |
摘要 |
<p>An ageing process capable of producing an aluminum alloy with better mechanical properties than possible with traditional ageing procedures. The ageing process employs a dual rate heating technique that comprises a first stage in which the aluminum alloy is heated at a first heating rate to a temperature between 100 and 170° C. and a second stage in which the aluminum alloy is heated at a second heating rate to a hold temperature of 160 to 220° C. The first heating rate is at least 100° C./hour and the second heating rate is 5 to 50° C./hour. The entire ageing process is performed in a time of 3 to 24 hours.</p> |
