RHENIUM-A PROMISING REFRACTORY METAL
The properties of rhenium and specialized applications of its alloys are discussed. Its mechanical properties are listed. When molybdenum-- rhenium alloys were used as filler metal in tungsten inert arc welding, resulting welds were found to have startling ductility at room temperature. Rhenium-- tungsten and rhenium -- molybdenum thermocouples provided a significant breakthrough in the accurate treatment of extremely high temperatures. Use of rhenium for electrical contacts was investigated. In heaters and filaments in electron tubes, the three principle advantages of rhenium over tungsten are that it has a greater resistance to the water-cycle effect, does not form stable carbides, and does not become brittle on recrystallization.
