Dynamic recrystallization behavior and microstructure evolution of high-Mn austenitic steel for application in a liquefied natural gas carrier

Journal of Materials Research and Technology, 2023
The hot-working behavior of high-Mn austenitic steel for liquefied natural gas carriers at the deformation temperature in the range of 1073–1273 K and the strain rate in the range of 0.01–10 s−1 was studied on a Gleeble-3800 thermomechanical simulator ...

Dynamic Recrystallization Behavior of Microalloyed 3.5Ni Steel [PDF]

, 2010
Both the critical conditions and evolution of dynamic recrystallization behavior for a Nb-Ti microalloyed 3.5Ni steel were carried out by isothermal compression deformation on a Gleeble-3500 thermal simulator. Results show that the critical conditions of

Tensile Testing with Cyclic Strain Holding to Analyze Dynamic Recrystallization of Pure Lead

Advances in Materials Science and Engineering, 2014
We analyzed the dynamic recrystallization of pure lead by tensile testing with cyclic strain holding at room temperature. The specimens were held at an identical strain and subsequently reloaded, providing the strength before and after the strain holding

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
