Prepared by powder injection molding Mo-Ti-Zr alloys, studies on thermal decomposition of carbon-molybdenum alloys and organizational impact. The results show that the carbon content is low, the alloy density is increased, and the carbon to form the dispersed second phase particles, such alloys have been strengthened; the carbon content is high, it is easy to add the elements molybdenum plating substrate and brittle second phase formed by the reaction particles, these second-phase particles in the fracture under tensile stress, coupled with the injection of the sample itself, there are more holes, cracks easily become a source of the alloy decrease in performance. Pyrolytic carbon can effectively prevent impuritiesowever, molybdenum has a low temperature brittleness, low strength, ductility and poor is insufficient, molybdenum alloy deep processing more difficult, its application is more restricted. Over the years, the production of Molybdenum Molybdenum primary products. Therefore, the development with better performance, higher value-added molybdenum alloys, molybdenum industry for the development of our country has an important significance.
Sun Jun engineering research group from the actual needs, dating back to the difficulty of material preparation techniques, revealing the rare earth oxide doped Molybdenum tube alloy grains and intragranular and grain boundary
Tungsten bars, rods, profiles and profiles plates, sheets, strip and foil of a deeper level of processing products export tariffs, so the 5% export tax rebate policy will continue. It can be understood, at least for now, for this type of tungsten production and exports, the country is still allowed, and even encouraged.
