Transformation to pearlite from austenitized and recrystallized austenite
Materials Science and Engineering, 1986Abstract The influence of hot deformation and austenization temperature on the subsequent isothermal transformation to pearlite was studied for 40Cr steel (which contains 0.38%C and 0.89%Cr). The deformation of austenite above its recrystallization temperature may accelerate or retard the subsequent pearlite transformation, and the decrease in ...

Thermodynamics of carbon in austenite and Fe-Mo austenite
Metallurgical Transactions A, 1976A Cahn Electrobalance has been used to determine directly and very accurately the carbon content of iron, iron-0.48 wt pct molybdenum and iron-1.16 wt pct molybdenum specimens which were equilibrated with a series of methane-hydrogen gas mixtures of constant composition.

New Protocol for Orientation Reconstruction from Martensite to Austenite in Steels
Materialia, 2019This work presents an approach for reconstructing the orientation of prior austenite using the martensite crystallography from an electron backscatter diffraction dataset.

Journal of Alloys and Compounds, 2013
Uniaxial tensile tests on a highly textured, fully austenitic stainless steel were performed in the transverse and rolling directions. Differences in overall material and transformation behavior were observed: transformation from the austenite phase to the martensite phase during a test in the transverse direction occurred at a higher strain and stress

Formation of austenite from a mixture of bainitic ferrite and austenite
Materials Chemistry and Physics, 1993Abstract In this work, the isothermal reaustenitization on a chemically homogeneous weld metal has been investigated with the purpose of studying the general trend of the kinetics. For this reheated weld metal, bainitic ferrite can form from small-grain austenite.

Austenitic solidification mode in austenitic stainless steel welds
Metallurgical Transactions A, 1979The micro- and macrostructures of about 50 different stainless welds of the AISI/AWS 300 series are analyzed. The results indicate that in welding condition corresponding to a typical SMA welding those and only those welds in which the ratio Creq/Nieq≲1.48, where Nieq and Creq are the nickel and chromium equivalents on the Schaeffler diagram, solidify ...

Strengthening austenitic steels by using nanotwinned austenitic grains
Scripta Materialia, 2012Abstract A novel strategy for strengthening austenite steels is introduced by using the unique strengthening effect of nanoscale twins. Austenite grains containing multiple nanoscale twins can be strengthened to a yield strength of a few GPa with very high work-hardening rates.

Simulation of Austenite Grain Growth in Low-Alloyed Steels upon Austenitization
Physics of Metals and Metallography, 2023A model has been developed that describes the grain growth upon austenitization, taking intoaccount the pinning of moving grain boundaries by carbonitride precipitates. The behavior of these precipitates is described using our previously developed approach for predicting the evolution of carbonitride particles.

Transformation to pearlite from hot-deformed and austenitized austenite
Materials Chemistry and Physics, 1987Abstract The influence of hot deformation and austenization temperature on the subsequent isothermal transformation to pearlite was studied for steels 40Cr and 50CrV. The deformation of austenite above or below its recrystallization temperature may accelerate the subsequent pearlite transformation.

Tensile ductility of nanotwinned austenitic grains in an austenitic steel
Scripta Materialia, 2014Dynamic plastic deformation followed by recovery annealing of an austenitic stainless steel results in the formation of a hierarchical microstructure consisting of nanotwinned austenitic grains (>55 vol.%) mixed with nanograins and dislocation structures.
