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 ...

Austenitization and Tempering Temperatures Effects on EUROFER 97 Steel

Materials Science Forum, 2018
EUROFER 97 is considered as standard steel for the nuclear applications in the case of high radiation density for first wall of a fast breeder reactors. Based on such consideration the microstructural behaviour of EUROFER 97 after thermo-mechanical processing is fundamental, since such materials properties are interesting also for innovative solar ...

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.

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.
