Effect of Thermomechanical Treatment on the Microstructure and Mechanical Properties of AISI 52100 Steel
Author: Clarence W. Schultz
Publisher:
ISBN:
Category : Mechanical engineering
Languages : en
Pages : 103
Book Description
The effects of various thermo-mechanical treatments on the microstructure and mechanical properties of AISI 52100 steel have been investigated using a combination of optical and transmission electron microscopy in conjunction with standard mechanical testing. The response of the as-treated material to various hardening and tempering treatments has been determined and compared to that of material processed using a standard commercial technique. The results indicate that the thermo-mechanical treatments examined refine the microstructure and increase the tensile strength of AISI 52100 steel. Using these treatments allows processing of the steel to be accomplished at lower austenitizing temperatures and in shorter times than in currently utilized techniques. Additionally, the degradation of mechanical properties by time at various tempering temperatures is reduced. (Author).

Modeling of the Microstructure and Mechanical Properties of Steels During Thermomechanical Processing
Author: Y.-W. Cheng
Publisher:
ISBN:
Category : Computer simulation
Languages : en
Pages : 72
Book Description
Models have been developed for the microstructural changes in C-Mn, vanadium-treated and eutectoid steels during thermomechanical processing. They relate processing parameters, such as strain, strain rate, and temperature to microstructural features, such as volume fraction of the recrystallized material and austenite grain size, with emphasis on the effect of microstructural changes on the mechanical properties of the final product. Model-predicted mechanical properties were compared with values measured in laboratory and industrial experiments. The models gave an accurate, quantitative characterization of the plates, rods, and rails subjected to rolling processes. The results of this study provide a basis for future optimization of the chemical composition and processing of steels.

Effect of Thermomechanical Processing on Microstructure, Texture, and Anisotropy in Two Nb Microalloyed Steels
Author: Abbas Akbarzadeh
Publisher:
ISBN:
Category :
Languages : en
Pages : 516
Book Description
"The process parameters that affect the anisotropy of mechanical properties of two Nb microalloyed linepipe steels (grades X-70 and X-80) were examined by controlled rolling and accelerated cooling on a pilot mill. The rolling schedules were first simulated by multi-pass torsion testing so as to determine the critical temperatures, such as T$ sb{ rm nr}$ and Ar$ sb3.$ Using the torsion test results, two finish rolling temperatures were chosen so as to be above and below the A$ sb3$ (in the $ gamma$ + $ alpha$ region). Two reheat temperatures were selected to study the effect of prior austenite grain size. The properties of air cooled samples are compared with those of specimens cooled at two different rates; in each case, cooling was interrupted at one of three different temperatures. The textures were measured by x-ray diffractometry and are presented in the form of ODF plots and skeleton lines. The yield strengths were measured by carrying out tensile tests along directions inclined at increasing angles to the rolling direction." --
