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.

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'.

High‐temperature compression deformation behavior of the Inconel 625 alloy is investigated using hot compression tests. The results regarding the flow behaviors and hot processing map indicate that the optimum condition for plastic deformation is determined to be at temperatures higher that 1050 °C and strain rate from 1 to 10 s−1.

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 and Engineering: A, 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.

Hot deformation behavior of hot extruded Al–6Mg alloy
Materials Science and Engineering: A, 2012Abstract The behavior of hot extruded Al–6Mg during hot deformation has been studied using hot compression test. The tests were performed at temperatures of 350, 450, and 550 °C and strain rates of 0.001, 0.1, and 1 s−1. Due to the effects of friction and adiabatic heating generated during compression, the attained true stress–true strain curves have
