Abstract The first step in the hardening of steel is getting it hot enough to form austenite, from which martensite can form upon quenching. Not all steels have the same austenitization requirements, however. High-carbon wear-resistant steels, such as bearing and tool steels, require the presence of carbides during austenitization; plain

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.

Abstract This chapter examines the structural changes that occur in high-carbon steels during austenitization. It describes the effect of heating time and temperature on the production of austenite and the associated transformation of ferrite and cementite in eutectoid, hypoeutectoid, and hypereutectoid steels.

Metals and Materials International, 2015
The effect of the austenite phase on mechanical properties of austenitic stainless steels was investigated using specimens with different volume fractions of retained and reversed austenite. Stainless steels with dual-phase coexisting martensite and austenite were successfully synthesized by deformation and reverse transformation treatment in the cold ...

AbstractAustenitization refers to heating into the austenite phase field, during which the austenite structure is formed. This article highlights the purpose of austenitization, and reviews the mechanism and importance of thermodynamics and kinetics of austenite structure using an iron-carbon binary phase diagram.

Ferritic-austenitic solidification mode in austenitic stainless steel welds
Metallurgical Transactions A, 1980The macro-and microstructures of about fifty different stainless welds of the AISI/ AWS 300 series are analyzed. The results indicate that under conditions corresponding to a typical shielded metal arc (SMA) welding the welds with a ratio in the range 1.48≾Cr eq /Ni eq ≾1.95, where Ni

Thermal and Mechanical Stability of Austenite in Metastable Austenitic Stainless Steel
Metallurgical and Materials Transactions A, 2019The roles of grain size, texture, strain, and strain rate on the thermal and mechanical stability of austenite in AISI 321 metastable austenitic stainless steel were studied. Ultrafine grain (UFG), fine grain (FG), and coarse grain (CG) specimens with average grain sizes of 0.24, 3, and 37 µm sizes, respectively, were investigated.

Austenite texture and bainite/austenite orientation relationships in TRIP steel
Scripta Materialia, 2001Abstract A bainitic medium carbon steel with 10–15 vol.% of retained austenite has been used to measure the texture of recrystallised and deformed austenite and of the corresponding bainite. The local orientations of bainite and retained austenite, and their orientation relationships, have been measured with an automated EBSD device mounted on a FEG ...
