wire and rods only industrial production methods

1910 has started using powder metallurgy production of molybdenum products. 1945 has been manufacturing powder metallurgy molybdenum sheet, wire and rods only industrial production methods. The mid-1940s the United States Parker (RParke) and Hamm (JLHam) developed into a consumable arc melting process of preparing high performance molybdenum and Molybdenum tube alloy ingots approach. The late 1940s to the mid-1960s, in order to meet the nuclear, aviation and aerospace technology needs, molybdenum alloys and related processes have been extensively studied, developed Mo-0.5Ti-0.02C alloy, Mo-0.5Ti-0.1Zr-0.02 C (TZM) alloys. The late 1960s to the early 1970s and made ​​from higher-strength Mo-Hf-C alloys. China began in the late 1950s produced by powder metallurgy blank molybdenum products. After two kinds of powder metallurgy and smelting and alloy billet production of molybdenum rod, wire, sheet, foil, tubes and rectangular tubing.as well as for the production of die-casting and extrusion dies, spacecraft parts. Because molybdenum alloy welding low temperature brittleness and fragility, and the high-temperature oxidation, so their development is restricted. Industrial production of molybdenum alloys, molybdenum and titanium zirconium, molybdenum, tungsten and molybdenum, rare earth alloy, used more often is the first class. Molybdenum alloy is the main way to strengthen the solid solution strengthening, precipitation strengthening and work hardening. Can be obtained through the plastic processing molybdenum alloy sheet, strip, foil, tubes, rods, wire and profiles, but also improve its strength and improve the low temperature ductility.
