Published 1991Staff ViewISSN: 1573-4889Keywords: plasma nitriding ; Fe-18Cr-9Ni ; CrN precipitates ; nitrogen diffusion ; kineticsSource: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract To clarify the mechanism of plasma nitriding, we examined the optical microstructure, the hardness, the precipitation, and the concentration of dissolved nitrogen in Fe-18Cr-9Ni nitrided using plasma in the range of 723–823 K. Compared with ammonia-gas nitriding, the features of plasma nitriding are the formation of small chromium-nitride precipitates (CrN), the absence of an externally nitrided layer, the high concentration of dissolved nitrogen, and the high hardness (HV=1200). The diffusion coefficient of nitrogen in the present alloy was determined using the growth rate of the internally nitrided layer, based on calculations used in internal oxidation. Plasma- and gas-nitriding were also compared with respect to the growth rate of the nitrided layer.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The plasma nitriding behaviour of Fe-18Cr-9Ni alloy was compared with gas nitriding. The alloy was nitrided under the following conditions: specimen temperature: 823 K, nitriding time: mainly 108 ks, total pressure: 0.4–0.7 kPa, mixture ratio of N2 and H2∶ 0.25, discharge voltage: 350–450 V, current: 0.8–1.1 A. Formation of a surface layer of iron nitrides was not observed. Formation of a homogeneous internal nitriding layer, consisting of small precipitates of CrN and the γ-phase matrix, was, however, noted. The lattice constant at the specimen surface was smaller than that at greater depth. This may have been because the sputtering effect decreased the dissolved nitrogen content at the specimen surface. The sputtering of iron nitrides at the specimen surface by the plasma was experimentally confirmed through γ′-Fe4N formation on Si beside an alloy specimen. The characteristics of the plasma nitriding mentioned above are discussed in relation to the sputtering.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-6036Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract By introducing a new type of decoupling approximation within the framework of an effective field theory, we discuss the critical temperature of an isotropic square and simple cubic lattice in an Ising model. It is also derived the critical value Δ c above which the magnetism occurs in a free surface of a semi-infinite medium. The present formalism yields results quite superior to the other effective fields theories and in good agreement with series expansions and exact's one.Type of Medium: Electronic ResourceURL:
