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 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.

Hot Deformation Behavior of AA-FGH720Li Superalloy

Materials Science Forum, 2017
The hot deformation behavior of FGH720Li superalloy was investigated by hot compressive tests on Gleeble-1500D thermal simulation test machine in different temperatures and strain rates. The true stress-strain curves were obtained, and based on the deformation data, the constitutive equation of FGH720Li superalloy was built.

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.

Hot Deformation Behavior of 316LN Stainless Steel

Advanced Materials Research, 2010
Hot-compression experiments of 316LN stainless steel have been conducted on a Gleeble-1500D thermal-mechanical simulator. We have analyzed the flow stress-strain curve and acquired the constitutive equation of 316LN steel by calculating stress exponent, activation energy and Zemer-Hollomon parameter.

Hot deformation behavior of hot-rolled AZ31 and AZ61 magnesium alloys

Materials Science and Engineering: A, 2014
Abstract The hot deformation behavior and microstructure of AZ31 and AZ61 alloys processed by the hot-rolled technique were investigated over a strain rate range from 1×10−4 to 1×10−1 s−1 and temperatures ranging from 350 to 500 °C. Alloys were manufactured by melting and casting, and then hot-rolled at two temperatures of 350 and 450 °C.
