Measurement and tailoring of residual stress in expanded austenite on austenitic stainless steel [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2017 Abstract Expanded austenite on stainless steel with a high interstitial nitrogen content is characterized by elasto-plastic accommodation of the large composition-induced lattice expansion leading to huge compressive residual stress. The elasto-plastic accommodation as well as the (steep) concentration profile has implications for the measurement ...

Thermal decomposition of N-expanded austenite in 304L and 904L steels
Surface Engineering, 2017 In this study, expanded austenite was prepared by an industrial low-temperature plasma nitriding process in 304L and 904L austenitic stainless steels. The current investigation focuses on the assessment of the thermal stability and related phase evolution of the expanded austenite layer during isothermal annealing in protective argon atmosphere at ...

ACS Applied Materials & Interfaces, 2013 Ferromagnetic single crystalline [100], [110], and [111]-oriented expanded austenite is obtained by plasma nitriding of paramagnetic 316L austenitic stainless steel single crystals at either 300 or 400 °C. After nitriding at 400 °C, the [100] direction appears to constitute the magnetic easy axis due to the interplay between a large lattice expansion ...

Characterization of expanded austenite developed on AISI 316L stainless steel by plasma carburization [PDF]
Surface and Coatings Technology, 2010 Expanded austenite generation through ion carburizing of AISI 316L using two different reactive gas mixtures (Ar 50%, H(2) 45%, CH(4) 5% and Ar 80%, H(2) 15%, CH(4) 5%) has been studied.

Thin Solid Films, 2017
Abstract Expanded austenite formed during low temperature plasma nitriding of austenitic stainless steels is known for its excellent wear and corrosion resistance. These wear and corrosion properties may degrade by exposure of the surface hardened steel to high temperatures, between 400 °C and 700 °C.

INSTRUMENTED MICROSCRATCH TESTS USAGE FOR STUDY OF EXPANDED AUSTENITE PROPERTIES [PDF]
Tecnologia em Metalurgia, Materiais e Mineração, 2015 Corrosion resistance and poor mechanical properties are both characteristics of AISI 316 austenitic stainless steel. Nitrogen supersaturated expanded austenite, or S-phase, promotes surface hardening of the alloy without the formation of undesirable ...
