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

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.

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.

Abstract The effect of short re-austenitizing cycles at various temperatures on the average austenite grain size, the formation of carbides, the austenite stabilization and the kinetics of the bainite transformation in three model steels was studied. Optical and electron microscopy and X-ray diffraction showed that the austenite grain size decreases ...

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

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.

Abstract This chapter addresses the issue of retained austenite in quenched carburized steels. It explains why retained austenite can be expected at the surface of case-hardened components, how to estimate the amount that will be present, and how to effectively stabilize or otherwise control it. It presents detailed images and data plots

Abstract This article discusses the composition, processing, and properties of austenitic manganese steel. Austenitic manganese steel is used in equipment for handling and processing earthen materials, such as rock crushers, grinding mills, dredge buckets, power shovel buckets and teeth, and pumps for handling gravel and rocks.

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.
