Transformation to pearlite from austenitized and recrystallized austenite

Materials Science and Engineering, 1986
Abstract 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 ...

Recrystallization of austenite

Metallurgical Transactions A, 1980
A 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.

Formation of austenite from a mixture of bainitic ferrite and austenite

Materials Chemistry and Physics, 1993
Abstract 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, 1979
The 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 ...

The influence of austenite texture on the martensitic transformation of an austenitic stainless steel

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

Strengthening austenitic steels by using nanotwinned austenitic grains

Scripta Materialia, 2012
Abstract 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.

Transformation to pearlite from hot-deformed and austenitized austenite

Materials Chemistry and Physics, 1987
Abstract 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, 2014
Dynamic 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.
