Focusing on the urgent need for large-scale high-performance molybdenum and molybdenum alloy products in the development of high-end medical equipment and nuclear power, in view of the difficulties in coordinating the various properties of existing domestic products, the difficulty in eliminating residual internal stress of large-scale products, and the poor uniformity of structure and performance, Insufficient strength and toughness and other problems, through the optimization design of multi-element and multi-phase molybdenum alloy configuration, the uniform preparation technology of special powder, the precise control technology of internal stress, inclusions and defects in the forming and sintering process of large-size molybdenum and molybdenum alloy ingots. Research on the channel torsion forging/rolling technology of molybdenum and molybdenum alloys, etc., and developed large-scale high-performance molybdenum and molybdenum alloy products for high-end equipment in the forming and sintering process of composition, matrix structure and second phase uniformity and size control technology, As well as key technologies such as complete sets of industrialized manufacturing technology, a large-scale molybdenum alloy bar production demonstration line with a production capacity of 600 tons/year and a large-scale molybdenum alloy plate production demonstration line with a production capacity of 400 tons/year have been built.
