Casting

Los Alamos researchers Deniece Korzekwa and Phil Tubesing position a cylindrical graphite funnel over a graphite mold used to cast pieces of uranium alloy. Thermocouples in the mold measure the temperature distribution during casting. (Thermocouple leads protrude from the mold.) Temperature data help researchers refine computer models of the casting process that will be used to improve the process. Proper casting helps produce alloy pieces that do not become brittle over long periods of time.
