Insight into the hot deformation behavior and recrystallization mechanism of Mg-Y-RE alloys based on machine learning

open access: yesJournal of Magnesium and Alloys
The hot deformation behavior of magnesium (Mg) alloys is significantly governed by the multi-physics coupling effects of temperature (T), strain rate (ε˙) and strain (ε), resulting in flow behavior that exhibits pronounced nonlinearity and multi-scale ...

Effect of repetitive upsetting-extrusion on deformation uniformity and mechanical properties of Mg–Gd–Y–Zr alloy

open access: yesMaterials Research Express, 2020
Mg-8.3Gd-3.2Y-0.4Zr alloy underwent severe plastic deformation at 420 °C using 4-pass isothermal repetitive upsetting-extrusion (RUE) process. The deformation uniformity in different regions of the same sample after 4 passes of RUE was studied.

Construction of meta-dynamic recrystallization dynamic model of 316L stainless steel based on grain orientation spread during continuous variable rate thermal deformation

open access: yesJournal of Materials Research and Technology
Because the deformation parameters (temperature, strain rate) in the actual manufacturing process are non-constant. We investigate meta-dynamic recrystallization behavior under the transient mutation state.
