Hot deformation‐enhanced globularization of pearlite
Steel Research, 1988A plain high‐carbon steel (0.74% C) was used to study the globularization (spheroidization and coalescence) of pearlite. In order to induce and/or enhance this process, specimens were deformed in the temperature range of austenite‐to‐pearlite transformation.

Hot deformation characteristics of 34CrMo4 steel
Journal of Iron and Steel Research International, 2010The 34CrMo4 (AISI 4130) steel is extensively utilized in the compressed natural gas cylinders. Due to the importance of thermomechanical processing in the production of these cylinders, the dynamic recrystallization (DRX) characteristics of 34CrMo4 steel were investigated.

Hot Deformation Behavior of Bearing Steels
Journal of Engineering Materials and Technology, 2007The material behaviors of two types of bearing steels at hot working conditions are investigated. Stress-strain curves at various temperatures (900–1300°C) and strain rates (1–50/s) are obtained by compression tests with a computer controlled servo-hydraulic Gleeble 3800 testing machine. Elongation and reduction of the area are also obtained by tensile

Predicting Hot Deformation of AA5182 Sheet
2012Aluminum 5000-series alloy sheet materials exhibit substantial ductilities at hot and warm temperatures, even when grain size is not particularly fine. The relatively high strain-rate sensitivity exhibited by these non-superplastic materials, when deforming under solute-drag creep, is a primary contributor to large tensile ductilities.

Microstructure development in hot deformed AA6082
Materials Science and Engineering: A, 2011Abstract Age hardenable aluminium alloys are suitable for hot deformation at temperatures between 300 and 600 °C, depending on the alloy and on the process. During thermo mechanical processes, dynamic and/or static restoration mechanisms take place. In this work, hot compression tests of hot rolled AA6082 and of a hot extruded AA6082 were carried out

Hot Deformation of Heat-Resistant Steels
2015The full recrystallisation temperature and the carbon-free bainite phase transformation temperature are determined by the slope-change points in the curve of mean flow stress versus the inverse of temperature. Constitutive equations including the stress exponent and an activation energy term are applied to analyse the hot deformation behaviour of ...
