Constitutive Models for Dynamic Strain Aging in Metals: Strain Rate and Temperature Dependences on the Flow Stress. [PDF]
Materials (Basel), 2020 A new constitutive model for Q235B structural steel is proposed, incorporating the effect of dynamic strain aging. Dynamic strain aging hugely affects the microstructural behavior of metallic compounds, in turn leading to significant alterations in their

Numerical modeling of the dynamic strain aging in steels at high strain rates and high temperatures [PDF]
EPJ Web of Conferences, 2021 Carbon steels can be heat treated to produce different microstructural variations and mechanical properties. At high temperatures the material plasticity and strength can be influenced by diffusional effects like the Portevin-Le Chatelier effect, leading

Mechanisms of types B and C serrations in the tensile flow curve of C-bearing high Mn steel
Journal of Materials Research and Technology, 2023 In the present study, the mechanisms of types B and C serrations in the tensile curves of C-bearing high Mn steel were investigated. Many tensile tests were performed at various temperatures (313–573 K) with two different initial strain rates (ε˙ini = 1 ×
