Further Analysis of Dynamic Strain Aging in Context of an Internal State Variable Constitutive Formalism

A Comprehensive Review of Experience with the Application of the Mechanical Threshold Stress Model

“…It is suspected that deformation twinning is effectively decreasing the grain size and leading to an increasing contribution from dislocation interactions with grain boundaries (e.g., the σ a variable in Equation ( 1)) [2]. Dynamic strain aging was observed to be prevalent in niobium, titanium, austenitic stainless steels, and nickel based superalloys [46]. Signatures of the contributions of these metallurgical processes in context of the application of the MTS formalism were noted [46].…”

Constitutive modeling and numerical simulations for dynamic strain aging in MMFX steel at elevated temperatures

“…There are several undesirable material characteristics associated with DSA such as reduction in fracture resistance and loss of ductility [4,7]. More details about the physics and characteristics of DSA can be found in the literature [3,4,17,20,21,28,35,37,58]. Therefore, it is scientifically and technologically important to understand DSA and its mechanism for a better quality of materials [42,45].…”
