Modeling thermomechanical processing of austenite

Journal of Materials Processing Technology, 2003
Abstract This work is divided into two parts. First, a mathematical modeling of the austenite transformation during deformation operations at high temperature is presented. The model introduced by Estrin, Mecking and Bergstrom is employed in predicting the dynamic recovery step while the additional softening by dynamic recrystallization is modeled ...

Thermomechanical processing of ferrous alloys

2005
Abstract Thermomechanical processing (TMP) refers to various metal forming processes that involve careful control of thermal and deformation conditions to achieve products with required shape specifications and good properties. This article describes TMP methods in producing hot-rolled steel and reviews how improvements in the strength ...

Kinetics of austenite transformation during thermomechanical processes

Canadian Metallurgical Quarterly, 1998
Abstract One of the most important fundamental problems of thermomechanical processing (TMP) of steel is the transformation kinetics of deformed austenite, which has a great influence on the final microstructure and mechanical properties. In the present work, the results of more than 20 years systematic study of deformation effects on the ferrite ...

Thermomechanical Processing of Thixomolded Alloys

2017
A wide variety of Mg alloys have been processed by Thixomolding ® followed by thermomechanical processing (TMP)—to increase tensile, creep and fatigue strength, ductility and formability. These alloys encompass variations in Al, Zn, Ca, Mn, Sr, Y, Zr and Rare Earths (RE) in the Mg base.

Thermomechanical processing of hydro-turbine steels

Journal of Materials for Energy Systems, 1980
An overview of the fabrication methods for the production of large hydraulic turbines is presented and the “fabricateweld” method for the production of large Francisturbine runners has been examined in detail. Tests for impact energy, fatigue and fracture toughness have been carried out in order to evaluate the cracking susceptibility.

Thermomechanical Processing of Medium Manganese Steels

Materials Science Forum, 2016
As third generation advanced high strength steels (AHSS) managing both high strength and good ductility/formability, medium manganese steels containing 3-7 wt% Mn have attracted attentions recently. However, the fundamental microstructure evolution during thermomechanical processing and heat treatments in medium-Mn steels is still unclear.

Thermomechanical Processes for Nonferrous Alloys

2005
Abstract The thermomechanical processing (TMP) of conventional and advanced nickel and titanium-base alloys is aimed at altering or enhancing one or more metallurgical features within the material and component. This article presents a number of examples of the TMP of nickel-base superalloys and titanium alloys.

Thermomechanical Processing of Metallic Glasses

2019
Depending on its thermal and kinetic history, a metallic glass (MG) of a given composition can show a wide range of energetic states. One central parameter determining the initial state of a glass is the cooling rate used to form it upon quenching from the melt.

Thermomechanical Processing of Ferrous Alloys

1978
Thermomechanical treatments have demonstrated great promise for increasing the strength and other mechanical properties of ferrous alloys. Various types of thermomechanical treatments can be defined, depending on the position in the heat-treatment cycle where the deformation is introduced. The characteristics of various treatments are briefly described.

Shock Thermomechanical Processing of Superalloys

1979
Nickel-base superalloys have become the primary material used in gas turbine engines for blades, brackets, disks, and other components. Most of the effort on nickel base materials has been to extend their high-temperature capabilities to increase the efficiency of the engine.
