    Inherent oxidation protection of Fe-5Cr-15Ni-2Si-4.5Mo (1987)
    Springer
    Oxidation of metals 28 (1987), S. 183-194 
    Details
    ISSN: 1573-4889
    Keywords: Oxidation ; silicon ; molybdenum

    Notes: Abstract The oxidation mechanism of Fe-5Cr-15Ni-2Si-4.5Mo alloy was investigated in order to determine the role of Si and Mo in providing oxidation resistance. It was determined that the oxidation protection in the temperature range 750–950°C resulted from formation of a continuous oxide sublayer of SiO 2 (or possibly Fe 2 SiO 4).Molybdenum formed an intermetallic Fe 2 Mo 1−x Si x that eventually diffused out into the grain boundaries and formed a protective barrier to the oxidation process. The mechanism behind the improved oxidation is the formation of a SiO 2 layer at the metal-oxide interface that retards the outward diffusion of Fe. It was also established that the oxidation mechanism was controlled by an activation energy equal to that of Fe 3+ ions diffusing through SiO 2.

    Oxidation behavior of Mn and Mo alloyed Fe-16Ni-(5-8)Cr-3.2Si-1.0Al (1990)
    Springer
    Oxidation of metals 33 (1990), S. 157-176 
    Details
    ISSN: 1573-4889
    Keywords: Fe-Ni-G-Al-S ; alloys ; Mo and Mn additions ; oxidation ; chromic scales

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Oxidation tests were conducted on a master alloy, Fe-16Ni-(5–8)Cr-3Si-lA1, to which (0–4) wt/o pct Mn and/or Mo were added. Tests were conducted at temperatures ranging from 1073–1273 K for times up to 1000 hr. Additions of Mn resulted in formation of a dual oxide structure and decreased oxidation protection. Addition of Mo significantly improved oxidation protection by formation of an intermetallic Fe(Mo)Si precipitate that eventually formed a protective SiO2 oxide sublayer. Increasing the Cr concentration in an alloy containing both Mn and Mo resulted in a slight increase in weight gain. To first order, the apparent oxidation activation energy for all the alloys was nearly constant, 121 kJ/mol, suggesting that the same mechanism controlled the oxidation for all compositions. The oxidation protection was related to the alloy components and concentration.

    Roll-bonded nitrogenated 201 stainless steel (1995)
    Springer
    Journal of materials science 30 (1995), S. 4103-4106

    Notes: Abstract An alternative to high-pressure melting was used to produce sheets of high-nitrogen stainless steel. Hot isostatic pressure diffusion of nitrogen into thin sheets of 201 stainless steel resulted in enhanced nitrogen concentrations unobtainable in commercial grade stainless steels. Several different nitrogen enhancement techniques were attempted. Hot roll-bonding was then used to produce thick laminates. The resulting tensile strengths were dependent upon the nitrogen concentration of the laminates and were similar to the tensile strength obtained for high-pressure melted nitrogen stainless steels.

    The microstructural properties of highly nitrogenated iron and iron-aluminum powders (1994)
    Springer
    Hyperfine interactions 92 (1994), S. 959-964 
    Details
    ISSN: 1572-9540
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A study has been made of highly nitrogenated pure iron and iron-aluminum alloy powder containing 2 wt.% Al (Fe-2Al) using Mössbauer spectroscopy and X-ray diffraction. The samples were prepared by high-temperature, high-pressure diffusion of nitrogen. They were prepared in a hot-isostatic-pressure (HIP) furnace at 1000 °C at nitrogen pressures up to 200 MPa. The alloy powders contained up to 8 at.% nitrogen as determined by vacuum fusion analysis. XRD analysis indicates that for the pure iron powders, the lattice spacing remained independent of nitrogen concentration, but that for the Fe-2Al powders, it decreased with increasing nitrogen concentration. Mössbauer analysis showed that for the pure iron powders, most of the nitrogen was associated with the formation of the iron nitride Fe4N. For the alloy powders containing less than 5 at.% nitrogen, all of the nitrogen was contained interstitially. The presence of nitrogen completely eliminated the conduction-electron spin-density oscillations observed in many ferromagnetic alloys.
