The nano-structured dispersion-strengthened molybdenum alloy has the microstructure of nano-rare-earth oxide reinforced particles and ultrafine grains, and the tensile ductility is doubled.

It is reported that China's molybdenum reserves, production and consumption rank first in the world. Molybdenum is widely used in the production of all kinds of steel materials such as stainless steel, molybdenum alloy also has a broad application prospect in aerospace, machinery, metallurgy and other fields because of its excellent thermal conductivity, high temperature resistance and other characteristics.

However, due to the low temperature brittleness, low strength, poor ductility and other deficiencies of molybdenum alloy, it is difficult to deep process molybdenum alloy, its application is greatly limited. For many years, China's molybdenum industry mainly produces molybdenum primary products. Therefore, the research and development of molybdenum alloy materials with better performance and higher added value is of great significance for the development of China's molybdenum industry.

Based on the actual engineering requirements and the difficulties of material preparation technology, the characteristics and mechanism of size effect of strengthening and toughening of grains, ingrain and grain boundary particles in rare earth oxide doped Molybdenum alloy were revealed, the quantitative analytical model of strengthening and toughening was established, and a new idea of strengthening and toughening by nano doping was put forward.

Based on this, the researchers developed a molecular level preparation containing nano rare earth oxides doped liquid mixing molybdenum alloy, the key technologies to solve the nano rare earth oxides and the aggregation, uniform dispersion in molybdenum grain interior and grain boundary distribution and the high temperature stability of ultrafine nano crystal structure and so on three key problems restricting the development of the field. The strength, elongation and toughness of the molybdenum alloy prepared by them have exceeded the best level of similar materials reported by international first-class companies. Meanwhile, the brittle transition temperature of the alloy is significantly reduced, and the high temperature recrystallization temperature, high temperature strength and tensile ductility of the alloy are significantly improved.
