Characterization of the expanded austenite developed on AISI 316 LM steel by plasma nitriding
AISI 316 LM samples were plasma nitrided at a temperature of 380°C for different times between 0.5 and 8 h in a 85%N2- 15%H2 gas mixture. Different experimental techniques such as: optical microscopy (OM), X- ray diffraction (XRD ) and glow discharge optical emission spectroscopy (GDOES) we...

| description | AISI 316 LM samples were plasma nitrided at a temperature of 380°C for
different times between 0.5 and 8 h in a 85%N2- 15%H2 gas mixture. Different
experimental techniques such as: optical microscopy (OM), X- ray diffraction
(XRD ) and glow discharge optical emission spectroscopy (GDOES) were used to
characterize the expanded austenite layer formed at the surface of AISI 316
LM stainless steel. The microscopical observations revealed the presence of
the expanded austenite with a mean layer thickness between 1.90 and 4.31 μm.
The growth kinetics of expanded austenite was also investigated. In addition,
both the compressive stresses in the expanded austenite layer and the
compositional strains were estimated by means of a simple mechanical model
based on the XRD results. |
