The Hot Deformation Behavior and Hot Processing Map of CL60 Rail Wheel Steel

Advanced Materials Research, 2012
The hot deformation behavior of CL60 rail wheel steel has been studied by employing both processing maps and microstructural observations. Tests are performed at temperatures of 800—1100°C and strain rates of 0.1s-1—5s-1 and the flow stress data obtained from the tests are used to develop processing maps.

Hot Deformation Behavior and Processing Maps of Zr92Ti8 Alloy

Journal of Materials Engineering and Performance, 2020
The hot deformation behavior of Zr92Ti8 alloy in the β-phase field was investigated by compression tests at deformation temperatures from 800 to 1050 °C and strain rates from 10−3 to 100 s−1. The true stress–strain curves exhibited a flow softening phenomenon caused by adiabatic heating and dynamic recrystallization (DRX).

Processing map for hot working of Inconel 718 alloy

Journal of Materials Processing Technology, 2011
Abstract Cylindrical specimens of Inconel 718 alloy with grain size of 90 μm were used in the compression tests and processing maps at the strains of 0.1, 0.3, 0.5 and 0.7 were developed at 950–1150 °C in the strain rate range 0.001–100 s−1. Only one unstable region for adiabatic shear bands and one small dynamic recrystallization zone in the stable ...
