Molybdenum alloy plastic processing is not only forming means

molybdenum plating alloy plastic processing is not only forming means, but also can improve the strength and molybdenum alloy to improve its low temperature ductility. Molybdenum and its alloys produced by conventional plastic processing methods sheet, strip, foil, tubes, rods, wire and profiles. Molybdenum alloy materials processing is characterized by hot deformation processing operations for each channel on the performance of the final product has a significant impact. Molybdenum oxidized rapidly above 600 ℃, at about 725 ℃ volatile oxidation products and the liquid phase appears, so molybdenum and alloys are commonly used for heating the hydrogen or other reducing atmosphere protection. Since thin layer of molybdenum contamination, use caustic to melt, the thermal processing may be carried out under atmospheric conditions, but to quickly appropriate. Molybdenum and alloys should be cold plastic - brittle transition temperature or higher.
Molybdenum and its alloys ingots produced mainly by powder metallurgy process can also be used smelting production process. Generally small size of the blank to use more powder metallurgy process, large-sized billets both can be used. Taken processes depend on the performance requirements of the final product. Suitable powder density of the blank of the theoretical density is about 93 to 96%. Industrial molybdenum and alloys used mainly vacuum consumable arc melting and electron beam melting. Coarse grains subject extrusion ingot blooming only after processing
