Hot Deformation Behavior of V-Microalloyed Steel

Journal of Iron and Steel Research International, 2010
Abstract Through the expansion curve of continuous cooling transformation at different cooling rates measured by THERMECMASTOR-Z thermal simulator for U75V rail steel, the continuous cooling transformation curve was obtained. The influence on steel microstructure and hardness at different cooling rates was studied.

Influence of Deformation Mode on Hot Deformation Behavior of CP Titanium

Materials Performance and Characterization, 2019
Abstract To obtain desired properties, the microstructure of metallic materials is tailored by subjecting them to different thermomechanical processing routes. In manufacturing industries, metallic materials are subjected to different hot deformation processes, viz, rolling, extrusion, and forging, during which materials undergo ...

Deformation behavior of AA2017–SiCp in warm and hot deformation regions

Materials & Design, 2015
Abstract In this work, the flow stress behavior of a metal matrix composite AA2017–10% SiCp was studied by means of the uni-axial compression test. The composite was first produced by stir casting technique and then, hot extrusion with the ratio of 18:1 was carried out to achieve a microstructure with a homogeneous distribution of SiC particles.

Hot deformation behavior of ZE41A magnesium alloy

Materials & Design, 2008
Abstract The deformation and failure behavior of ZE41A alloy in cast and heat treated conditions were investigated using tensile test at various temperatures, from 25 to 200 °C and at a strain rate range of 0.005–0.05 S −1 . The stress and strain corresponding to the fracture were estimated.

Deformation behavior of Waspaloy at hot-working temperatures

Scripta Materialia, 2004
Abstract Isothermal, hot-compression tests were conducted on single crystals of a typical nickel-base superalloy, Waspaloy, to establish the slip systems that operate during hot working. Slip-trace analysis and flow-curve measurements revealed that deformation occurred via classical octahedral ({1 1 1}〈1 1 0〉) slip.

Hot Deformation Behavior of Bearing Steels

AIP Conference Proceedings, 2004
The material behaviors of two types of bearing steels at hot working conditions are investigated. Stress‐strain curves at various temperatures (900∼1,250°C) and strain rates (1∼50 /sec) are obtained by compression tests with a computer controlled servo‐hydraulic Gleeble 3800 testing machine.

Hot Deformation Behavior and Microstructure of U720Li Alloy

Advanced Materials Research, 2013
The hot deformation behavior of U720Li was investigated by isothermal compression tests at temperature ranging from 1060-1180°C and strain rate from 0.001s-1 to 20s-1. The flow stress-strain curves and microstructures were investigated and a constitutive equation was established.

Hot Deformation Behaviors of SiCp/Al Composites

Advanced Materials Research, 2014
The hot deformation behaviors of 30%SiCp/2024 aluminum alloy composites was studied by hot compression tests using Gleeble-1500 thermomechanical simulator at temperatures ranging from 350-500°C under strain rates of 0.01-10 s-1. The true stress-true strain curves were obtained in the tests. Constitutive equation and processing map were established. The

Hot Deformation Behavior of F6NM Stainless Steel

Journal of Iron and Steel Research International, 2014
The hot deformation behavior of F6NM stainless steel was investigated by hot compression test in a Gleeble-1500D thermal-mechanical simulator. The flow strain-stress curves were obtained and the corresponding metallographic observation of this steel under different deformation conditions was also carried out.
