with the extension of molybdenum alloy strength

Sun Jun Task Force revealed the rare earth oxide doped molybdenum alloy grains and intragranular and grain boundary characteristics and particle size effect toughening mechanism, a toughening of quantitative analytical model proposed toughening of nano- doped new ideas . Copper Lead Zinc Tin CNMN.COM.CN nickel , small metal , scrap metal. On this basis , Sun Jun research group has developed a molecular liquid doped rare earth oxides prepared by mixing nano- molybdenum alloy containing key technologies to solve the rare earth oxide nano- technology and non- reunion , and the Molybdenum tube grain internal and uniformly dispersed grain boundaries , as well as nano- ultrafine grain structure constraints such as high temperature stability of development of the sector three "bottleneck" problem. Copper Lead Zinc Tin CNMN.COM.CN nickel , small metal , scrap metal. The prepared alloy oxide having an average particle size of less than 80nm, molybdenum submicron grain size can be , with the extension of molybdenum alloy strength , toughness more than world-class companies have reported similar materials best level , while significantly reducing their plastic brittle transition temperature , and significantly improves the recrystallization temperature of the alloy at elevated temperature and high temperature tensile strength and ductility . Copper Lead Zinc Tin CNMN.COM.CN nickel , small metal , scrap metal.
The project-related technology has been in Jinduicheng Molybdenum Company to achieve a scale applications, has achieved remarkable economic and social benefits , and access to 2012 Department of Education Technology Invention Award . Copper Lead Zinc Tin CNMN.COM.CN nickel , small metal , scrap metal. The research was supported by the National Natural Science Foundation of China and other countries co-financed projects
