  • Vapor phase uphill quenching of metal alloys using fluorochemicals
    Patent number: 4968358
    Abstract: Uphill quenching of metal alloys, such as aluminum alloys, is improved by conducting the heating step, after the quench-cooling step of the uphill quenching, using the elevated temperature vapor of a fluorochemical compound, preferably a perfluorocarbon compound. The vapor formed over a boiling bath of the perfluorocarbon compound comprises the heat source when it condenses on the relatively cooler alloy thus imparting its heat of condensation to the alloy.
