Significance of Deformation Mode in Hot Deformation
Materials Science Forum, 2000In order to study strain path effects, hot deformation tests must be carried out utilising different combinations of compressive, tensile and shear strains. However, before the results from these tests can be reliably interpreted, it is important to carry out deformations in simple tension, compression and torsion as a 'baseline'.

Hot Deformation Behavior of Hot-Extruded AA7175 Through Hot Torsion Tests
Journal of Nanoscience and Nanotechnology, 2018The hot deformation behavior of hot-extruded AA7175 was investigated with flow curves and processing maps through hot torsion tests. The flow curves and the deformed microstructures revealed that dynamic recrystallization (DRX) occurred in the hot-extruded AA7175 during hot working. The failure strain was highest at medium temperature.

Physical Simulation at Hot Deformation
Materials Science Forum, 2010Today the numerical simulation of hot deformation processes is very advanced. But it requires mathematical models for metalphysical processes as for microstructure development, which take place during the deformation. Until now such models were developed for many steel grades and non-ferrous materials.

Hot-deformation characteristics of Waspaloy
Materials Science and Technology, 1985AbstractSpecimens of wrought Waspaloy have been reheated to above the γ' solvus temperature and tested in plane-strain compression at constant equivalent tensile strain rates in the range 0.5–50 s−1, and at initial test temperatures in the range 960–1070°C. The majority of tests were conducted with the tools and test environment at 850°C.

Hot deformation behavior and deformation mechanism of two TiAl-Mo alloys during hot compression
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2018Abstract Two TiAl alloys with different Mo contents (Ti-44Al-4Nb-1.0Mo-0.1B-0.01Y, and Ti-44Al-4Nb-1.5Mo-0.1B-0.01Y, referred to LM and HM alloys, respectively) are prepared, and their hot deformation behaviors are characterized via hot compression tests.

Deformation Behavior of Glass Nanostructures in Hot Embossing
ACS Applied Materials & Interfaces, 2020In the nanoscale glass formation, the flow and deformation behavior of glass materials are quite different from those in the macroscale because the mold cavity influences the viscous flow behaviors of glass because of the size effect. The knowledge of macroglass molding process no longer applies to the fabrication of glass microparts by hot embossing ...

Deformation mechanisms in hot working
JOM, 19681. During deformation at a constant temperature above 0.5Tm, there is a steady-state regime where both stress and strain rate remain constant independent of strain. 2. The interdependence of stress, strain rate and temperature during steady-state hot working and secondary creep are similar. 3.

A model for static recrystallization after hot deformation
Acta Metallurgica, 1975Abstract A model for static recrystallization following hot deformation is developed by generalizing a previous model for hor working. In particular, the consequences of hot working occurring by dynamical recrystallization on static recrystallization are investigated.
