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.

Metallurgical and Materials Transactions A, 2005
The effect of prior-austenite grain size and transformation temperature on nodule size and colony size of hypereutectoid steels containing 1 pct carbon with different levels of vanadium and silicon was investigated. Specimens of the various steels were thermally processed at various temperatures ranging from 900 °C to 1200 °C and transferred to salt ...

Factors affecting prior austenite grain size in low alloy steel
Journal of Materials Science, 2006The effect of varying normalising and hardening temperatures on the prior austenite grain size in a low alloy Cr–Mo–Ni–V steel has been examined. An initial relative insensitivity of grain size to increasing austenitising temperature was observed followed by a sudden growth of grains at approximately 1000 °C. A detailed study of the precipitates in the

Influence of Repeated Quenching After Carburizing on Prior Austenite Grain Size
Materials Science Forum, 2007High strengths and impact values are required for carburizing steels used for automotive drive train parts. It is well known that the finer-grain microstructures are favorable for these properties. In this study, with a view to effective refining of grain size with controlling the alloying elements, influence of Mn and Cr content on prior austenite ...

Effect of prior austenite grain size on isothermal bainite transformation in 65Cr steel
Materials Letters, 2020Abstract Isothermal bainite transformation was conducted on both ultrafine-grained (UFG) and normal-grained (NG) 65Cr steels. Both bainite morphology and transformation rate are greatly influenced by prior austenite grain size. Bainite transformation rate is greatly retarded in the UFG steel with average grain size of 4.6 μm.

Effect of Prior Austenite Grain Size on the Morphology of Nano-Bainitic Steels
Metallurgical and Materials Transactions A, 2018The strength in nanostructured bainitic steels primarily arises from the fine platelets of bainitic ferrite embedded in carbon-enriched austenite. However, the toughness is dictated by the shape and volume fraction of the retained austenite. Therefore, the exact determination of processing–morphology relationships is necessary to design stronger and ...

The effect of austenitising temperature on prior austenite grain size in a low-alloy steel
Materials Science and Engineering: A, 2008Abstract The effect of varying normalising and hardening temperatures on the prior austenite grain size in a low-alloy Cr–Mo–Ni–V steel has been examined. An initial relative insensitivity of grain size to increasing austenitising temperature was observed followed by a sudden growth of grains at approximately 1000 °C.

Simulation of the influence of phosphorus on the prior austenite grain size of high-impurity steels
Acta Materialia, 2006Abstract The effects of phosphorus addition on the phase transformation behavior of low-carbon steels were analyzed using a computational simulation focusing on the micro-segregation behavior of phosphorus during solidification and subsequent cooling processes. Based on the results of the simulation, a fully theoretical approach to modeling austenite
