Thermodynamics of carbon in austenite and Fe-Mo austenite [PDF]
Metallurgical Transactions A, 1976 A 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.

Sliding wear of austenitic and austenitic-ferritic stainless steels
Metallurgical and Materials Transactions A, 2002The dry sliding behavior of a 304L austenitic stainless steel and a duplex 2205 austenitic-ferritic stainless was investigated. The evolution of wear was characterized by the existence of a sliding-distance transition. In particular, wear passed from delamination to tribo-oxidation, with a reduction in wear rate. The occurrence of such a transition was

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 ...

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.

Recrystallization of austenite
Metallurgical Transactions A, 1980A laboratory simulation of hot-rolling schedules, which employs a sequence of high-speed compressions performed over a range of temperatures, was used to determine the effects of composition and processing variables on the state of the austenite at several points in the hot-rolling procedure.

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

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 ...
