Metal fume fever metals, such as chromium, vanadium and cerium. Cadmium is often replaced by other metals. Zinc or nickel plating can be used instead of cadmium plating, and brazing filler alloys now rarely contain cadmium. Metal fume fever Metal fume fever, also known as brass founders' ague, brass shakes, zinc shakes, galvie flu, metal dust fever, Welding Shivers, or Monday morning fever, is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (AlO), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are heated. Other common sources are
Microstructurally stable nanocrystalline alloys Microstructurally stable nanocrystalline alloys Microstructurally stable nanocrystalline alloys are alloys that are designed to resist microstructural coarsening under various thermo-mechanical loading conditions. Many applications of metal materials require that they can maintain their structure and strength despite very high temperatures. Efforts to prevent deformations from long term stress, referred to as creep, consist of manipulating alloys to reduce coarsening and migration of individual grains within the metal. The small size of individual metal grains provides high interfacial surface energy which is what prompts coarsening, the increase in grain size, and eventually metallic softening. Nanocrystalline creep is considered to follow the
