Numerical predictions of orthogonal cutting–induced residual stress of super alloy Inconel 718 considering dynamic recrystallization

Abstract Manufacturing processes, such as machining, can produce residual stresses in products. Residual stress and its distribution be the main factor influencing fatigue life of machined components has already been subject many experimental numerical studies. The high-temperature condition, a result makes change microstructural properties material consequently affect mechanical workpiece. A major metal component aircraft structure engine is nickel-based alloys due to their resistance heat, corrosion, thermal fatigue, shock, creep, erosion. When these critical structural aerospace industry are manufactured with objective reach high-reliability levels, surface integrity one most relevant parameters used for evaluating quality finish-machined surfaces. alterations including white layer, depth work hardening, micro-cracks, oxidation induced by machining extremely safety sustainability concerns. Integrated Computational Materials Engineering (ICME) links physics-based models predict performance materials based on processing history. Johnson–Mehl–Avrami-Kolmogrov (JMAK) model develop microstructure-based modeling approach that takes into account dynamic recrystallization (DRX) causes grain size changes. Allied that, parameter flow behavior considered adding size-dependent term traditional Johnson–Cook (JC) novel framework. impact simulation orthogonal cutting process implemented finite element method (FEM) model–based commercial software, ABAQUS-explicit, coupled Euler-Lagrangian (CEL) approach. By relying VUHARD user subroutine capabilities Fortran language, ABAQUS-explicit steered considering DRX. forecast capability developed assessed comparison results changing cut edge radius effect stress. Then, correlation between evolution temperature velocity investigated.
