Ordering kinetics of Fe3Pt austenites and reversed austenites
Metallurgical Transactions A, 1980Fe3Pt austenites undergo an ordering reaction belowT c in addition to the martensite transformation at a much lower temperature. It is to be expected that theM s temperature will be affected by the degree of austenite order and the progress of austenite ordering can be conveniently represented by the variation ofM s temperature.

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.

A cold-rolled 10 wt% Mn steel was austenitized before intercritical annealing. Austenite and ferrite fractions and austenite stability remained equivalent to those of the non-austenitized counterpart.

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

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.
