Nitride can be formed to strengthen the Co-based alloys
Conductivity greater than 10. . a-SiG ~: H film of the light / dark conductivity greater than 10 (when the band gap of less than 1.4eV), and H-bonding is mainly GeH. This allows the two materials are suitable for three-junction amorphous silicon solar cell manufacturing. Also made out of polycrystalline CC. Membrane (accounting for Ge and C grid), not mixed with the GC membrane structure is also ordered materials with strong absorption,moncler italia, decreased after addition of high concentrations of lattice order,ugg italia, but enhances its efficiency of light absorption Therefore, this material is an excellent material photonic devices. On this material, the film the relationship between the nature and concentration worthy of further study. (Deng Zhijie Excerpt) y,, ¨ vV3 gradually profile beech '≯ /,'/,,, nitrogen compounds can be formed to strengthen the United States of cobalt-based alloy Haynes International, Inc. is developing a new type of deformation of cobalt alloy, by adding nitrogen titanium and niobium nitride dispersed phase enhancement, can be used for sheet metal applications. The company's goal is to develop a project with a sheet of high temperature strength alloys, but also has the performance of existing alloys. , Called Haynes NS. 163 of the new alloy at 900 ℃ in the stress of 70MPa, the stress rupture life is greater than 1000h. At 982 ~ C and 55MPa stress, the stress rupture life is greater than 250h. NS is a composition of the alloy Co 163 a 28Cr a 9Ni a 21Fe-l-25Ti a 1Nb. Alloy high temperature alloy using the traditional process, using vacuum induction melting and electroslag remelting method of preparation. Alloy sheet using the traditional hot and cold rolling to manufacture, forming and welding parts using traditional methods to manufacture. However, the addition of titanium nitride and niobium nitride relative dispersion components unique final heat treatment can completely nitrided parts. This treatment makes alloy parts with exceptional creep / rupture strength. (Wang Fenge translation) can be thermoplastic composite materials instead of metal, according to reports, the Belgium Quadrant Engineering Plastic Products has developed a new technology, the incorporation of glass fiber reinforcing agent in the polymer matrix, can greatly improve the range of plastic sheet and Thick structural strength. The hardness increases,piumini Moncler, the new thermoplastic composite (TPC) in the limited application of structural strength than the metal and thermosetting plastic has more advantages, because in these applications by the thickness of the material cost constraints. The results show that the metal parts of thermoplastic composite materials can reduce the weight of 50%, but the structural strength of the metal is very close. Polypropylene compounds for testing to confirm the ongoing structural components mount equipment performance, reduce weight and energy requirements. The thermoplastic composite material processing and energy transfer in the application of transmission is also being evaluated, such as for transmission, to reduce the noise more than the superiority of metal parts. (Wang Fenge Excerpt) NbC nano-state diffusion can be strengthened austenitic steels Oak Ridge National Laboratory's Materials Science and Technology Division developed a series of cheap, 0, amorphous,giubbotti moncler, high-creep strength austenitic stainless steel. Alloy from the Fe. 20Ni. 14Cr-2.5AI composition, and with the state of dispersion of nano-niobium carbide in order to strengthen. These alloys have the potential to significantly improve the structural elements of the temperature,rosetta stone spanish, and energy conversion device is in the erosion of 7 相关的主题文章: Foreign R & D program _8534 superconducting giubbotti moncler Jingdezhen LED lighting industry base construction _6349 ugg italia Japan's 2008 demand forecast for semico |
