Thermomechanical processing of 42CrMoS4 steel
International Heat Treatment and Surface Engineering, 2010AbstractBillets of 42CrMoS4 steel were subjected to a programme including forging and rolling to different reduction ratios, followed by quenching and tempering to simulate online thermomechanical treatment (TMT) during rolling. The mechanical properties obtained were compared with those obtained by conventional heat treatment (CHT) (quenching from 860°

Processing, Microstructure, and Thermomechanical Behavior of Ceramics [PDF]
Advanced Engineering Materials, 2001 A global approach to ceramics, including the effect of processing on microstructure and of microstructure on final properties, is needed in order to extend the use of ceramic materials. The application of such an approach is demonstrated to different types of ceramics.

Thermomechanical Processing of Aluminium Alloys
1998Over 50% of the aluminium alloys produced by industry undergo subsequent mechanical working and annealing (thermomechanical processing or TMP), in order to produce a fmished or semi-fmished product. This type of processing is also important for many other metals, e.g. the forging of nickel and titanium alloys for aerospace applications, and is becoming

Thermomechanical Processing beta Titanium
1973Abstract : on polygonized structures, the effects of cold-reduction temperature, and multi-stage aging. Combinations of strength and ductility can be manipulated within a wide range by varying the amount of cold work and the aging treatment. Mechanical properties are strongly dependent upon the mode of deformation during cold working and slight ...

Recrystallization during Thermomechanical Processing of IMI834
Metallurgical and Materials Transactions A, 2008The microstructure development of the near-α titanium alloy IMI834 displaying an initial bimodal α + β microstructure has been characterized with respect to dynamic and static β recrystallization, through quantitative metallography. The investigation was supplemented by interrupted compression testing, to evaluate the applicability of fractional ...

Thermomechanical Processes for Nonferrous Alloys
2005Abstract 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.

Investigation of thermomechanical processes in the course of polishing
Materials Science, 1996We study the contact problem of thermoelasticity for a half plane. The function that describes the profile of the stamp is represented in the form of a series in Jacobi polynomials. Heat is produced as a result of the work of friction forces in the region of contact.

Simulation of thermomechanical processes in crystallizing polymer
Polymer Engineering & Science, 1997AbstractConstitutive equations are developed to describe the interrelation between thermomechanical behavior and phase transitions in crystallizing polymers. A crystalizing polymer is considered as a two‐component mixture of amorphous and crystalline structures, the fraction of which is defined by the degree of crystallinity.

A holistic approach to thermomechanical processing of alloys
Sadhana, 2003New process design and control methods are needed for significantly improving productivity and reducing costs of thermomechanical processes such as hot metal forging. Current practices for accomplishing basic design tasks such as selecting the number of forming steps and specifying the processing conditions for each thermomechanical operation produce ...
