On the elusive crystal structure of expanded austenite [PDF]

Scripta Materialia, 2017
Abstract No consistent structural description exists for expanded austenite that accurately accounts for the hkl -dependent peak shifts and broadening observed in diffraction experiments. The best available description for homogeneous samples is a face-centered cubic lattice with stacking faults. Here Debye simulations of stacking fault effects were

Expanded austenite, crystallography and residual stress

Surface Engineering, 2010
The identity of expanded austenite as developing during low temperature nitriding and/or carburising of austenitic stainless steel has been under debate since the very first observation of this phase. In the present article, recent results obtained with (a) homogeneous samples of various uniform compositions and (b) unravelling of the contributions of

Determination of the concentration dependent diffusion coefficient of nitrogen in expanded austenite

International Journal of Materials Research, 2008
AbstractThe concentration dependent diffusion coefficient of nitrogen in expanded austenite was determined from the rate of retracting nitrogen from thin initially N-saturated coupons. Nitrogen saturated homogeneous foils of expanded austenite were obtained by nitriding AISI 304 and AISI 316 in pure ammonia at 693 K and 718 K.

Composition-dependent variation of magnetic properties and interstitial ordering in homogeneous expanded austenite [PDF]

Acta Materialia, 2016

Comparison of expanded austenite and expanded martensite formed after nitrogen PIII

Surface and Coatings Technology, 2004
Abstract The formation of expanded austenite is a well-established phenomenon after energetic nitrogen ion implantation into austenitic steel or nickel alloys, correlated with a very high surface hardness and wear resistance. Using high-voltage PIII implantation into martensitic stainless steels, it is also possible to form expanded martensite.

On the Carbon Solubility in Expanded Austenite and Formation of Hägg Carbide in AISI 316 Stainless Steel [PDF]

Steel Research International, 2016
The carbon solubility in expanded austenite is investigated by controlled low temperaturegaseous through-carburizing of AISI 316 stainless steel thin foils with thermogravimetry and synchrotron powder diffraction analysis.

Microstructure of perfect nitrogen-expanded austenite formed by unconstrained nitriding

Scripta Materialia, 2021
Abstract In present work, a perfect nitrogen-expanded austenite free from the deformation defect is prepared by the plasma-based low-energy nitrogen ion implanted (also named plasma source ion nitriding) TEM foil of Fe-Cr-Ni austenitic alloys under an unconstrained condition.
