Sliding wear of austenitic and austenitic-ferritic stainless steels

Metallurgical and Materials Transactions A, 2002
The 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

Simulation of Austenite Grain Growth in Low-Alloyed Steels upon Austenitization

Physics of Metals and Metallography, 2023
A 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.

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 ...

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.

Ordering kinetics of Fe3Pt austenites and reversed austenites

Metallurgical Transactions A, 1980
Fe3Pt 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, 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 ...
