Popis: | A method has been developed for producing nickel-molybdenum alloys with 28–50% Mo by a powder metallurgy process comprising hydrostatic pressing of mechanical Ni + Mo mixtures, sintering of resultant blanks, and their subsequent hot plastic working (forging or rolling) into rods and sheets. A study was made of the workability of nickel-molybdenum alloy blanks in forging and hot rolling. It was found that such alloys with 28–40% Mo are characterized by satisfactory, and NM45 alloy by poorer, workability, while NM50 alloy is not amenable to plastic working. Thus, the nonworkable (when produced by the conventional metallurgical process) 36–40% Mo alloys acquire satisfactory workability through the use of the powder metallurgy technique, which enables them to be employed in industry instead of molybdenum for operation in highly corrosive environments. |
