Temperature Effect on Deformation Response in Austenitic Stainless Steel

Defect and Diffusion Forum, 2022
Stress-strain behavior of austenitic stainless steel grade AISI 304 was investigated by means of uniaxial tensile tests and magneto-phase analysis. The test materials were strained in tension within the temperature range of-100 ≤ T ≤ +100 °C. According to the results, intensive strain hardening occurs in austenitic stainless steel when strain-induced α’

Surface modification of austenitic steels by low‐temperature carburization

Surface and Interface Analysis, 2012
Austenitic 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 ...

The Effect of Austenitizing Temperature on Prior Austenite Grain Size in Martensitic Cast Steel

Solid State Phenomena, 2013
The 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.

Structure and properties of a high-temperature austenitic steel at high temperatures

Russian Metallurgy (Metally), 2010
The structure of a high-temperature austenitic 12Kh15N16M2TR steel, which is promising for manufacturing steam superheater tubes, is studied after long-term thermal holding under stress. The type, morphology, and matrix arrangement of excess-phase particles that form during thermal holding are found.

Mechanical Properties of an Austenitic Stainless Steel at Elevated Temperatures

Journal of Constructional Steel Research, 1998
Publisher Summary This chapter presents an experimental research undertaken to analyze the mechanical properties of an austenitic stainless steel Polarit 725 at elevated temperatures. Two test series were carried out, one for the base material, and another for the cold-formed material.

Martensite start temperature and the austenite grain-size

Journal of Materials Science, 2010
The 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.

Néel temperature of high Mn austenitic steels

Metals and Materials International, 2012
The 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 ...

Austenite transformation in the intercritical temperature range

Metal Science and Heat Treatment, 1982
1. Austenitization temperature has the main effect on the amount of α-phase formed in the intercritical temperature range. As this temperature increases the amount of α-phase increases, approaching the calculated amount determined by the intercept rule. 2.

Austenite grain size and the martensite-start temperature

Scripta Materialia, 2009
New experimental evidence confirms the dependence of the martensite-start temperature on the austenite grain size. The Fisher model for the geometrical partitioning of austenite grains by plates of martensite is used here to develop a theory to explain the observations, based on the ability to detect transformation as a function of the austenite grain ...
