Surface modification of austenitic steels by low‐temperature carburization
Surface and Interface Analysis, 2012Austenitic stainless steels are characterized by good corrosion resistance in different environments, but their use is limited because of low hardness and poor wear resistance. Conventional thermochemical surface treatments for improving the mechanical strength of steels induce Cr carbide precipitation and thus are detrimental to ...

Néel temperature of high Mn austenitic steels
Metals and Materials International, 2012The predictive equations for the Neel temperature (TN) of high Mn austenitic steels were reviewed and reevaluated using 116 different measured TN values. The previous equations gave good predictions for TN values of high Mn-low C austenitic steels, but not for those of medium and low Mn-high C austenitic steels, including TWIP steels with less than 20 ...

Effect of Austenitization Temperature on Formation of Low Temperature Bainite
Advanced Materials Research, 2014The influence of austenitization temperature on the incubation period and bainitic transformation behaviours of the high-carbon silicon steel has been investigated. It was found that the nose temperature of bainite transformation and incubation period decreases with increasing austenitization temperature.

Low temperature ageing of FeN austenite
Acta Metallurgica, 1988Abstract Results are reported of the decomposition of nitrogen-stabilised f.c.c. iron at 210°C which has been studied by X-ray diffraction, Mossbauer spectroscopy and transmission electron microscopy. The unit cell dimension of the austenite phase remains constant over the period of ageing studied but changes are observed in both the Mossbauer ...

Austenitic Steels in High-Temperature Steam Piping
Journal of Fluids Engineering, 1957Abstract A review is presented of the operating experience and service difficulties with austenitic steel turbine piping at the 1050 F and 1100 F temperature levels. Reasons are advanced for the difficulties encountered and recommendations are made to prevent recurrence of these difficulties in future installations.

The Effect of Austenitizing Temperature on Prior Austenite Grain Size in Martensitic Cast Steel
Solid State Phenomena, 2013The GX12CrMoVNbN9-1 (GP91) cast steel belongs to a new group of high-temperature creep resistant cast steels being introduced to the power industry. The cast steel is characterized by higher mechanical properties in comparison with the low alloy Cr – Mo or Cr – Mo – V cast steels used so far.

Martensite start temperature and the austenite grain-size
Journal of Materials Science, 2010The dependence of the martensite start temperature on the austenite grain-size is modeled based upon aspects of martensite nucleation and validated by data reported in the literature. The results obtained support the view that grain boundaries provide an environment for the formation of martensite embryos in annealed austenite.
