The decomposition of Fe-Cr solid solutions during thermal aging is modeled by atomistic kinetic Monte Carlo simulations, using a rigid lattice approximation with pair interactions that depend on the local composition and temperature. are fitted ab initio calculations mixing energies vacancy migration barriers at 0 K. entropic contributions to alloys formation free taken into account. model reproduces change in sign energy alloy gives realistic thermodynamic properties, including an...
Nonequilibrium chemical redistribution in open systems submitted to external forces, such as particle irradiation, leads changes the structural properties of material, potentially driving system failure. Such is controlled by complex interplay between production point defects, atomic transport rates, and sink character microstructure. In this work, we analyze means a kinetic Monte Carlo (KMC) framework with an underlying atomistic model for Fe-Cr alloy study effect ideal defect sinks on Cr...
Thermomechanical modeling of additively manufactured parts made by laser powder bed fusion aims to control stresses and distortions built during processing. This is, nature, a multiscale metallurgical mechanical problem, notably due the strong texture grain structure that results from process may locally dictate thermomechanical behavior law. Similarly, are directly influenced heat transfer at system scale, including consequences link between part substrate weaker interactions with gas...
Purpose This paper aims to report on a homogenized model for the anisotropic thermal conductivity of support structures constructed by laser powder bed fusion (L-PBF) process, and its application numerical simulation L-PBF process. Design/methodology/approach Considering both analytical approaches, is developed across temperature interval encompassing entire Subsequently, material properties are incorporated into finite element (FEM) process consider effects structures, taking account their...
Iron-chromium alloys are the basis for ferritic and ferritic-martensitic steels that will be used in future fission (generation IV) fusion nuclear reactors. With Cr content between typically 8 to 12% [1], or even 14% matrix of some oxide dispersion-strengthened [2], one can expect precipitation a Cr-rich α’ phase strongly accelerated under irradiation, due point defect supersaturation. This cause hardening embrittlement. Radiation-induced segregation (RIS) is another important technological...
A theory of two-phase eutectic growth for a multicomponent alloy is presented. This employs the thermodynamic equilibrium at solid/liquid interface and thus makes it possible to use standard CALPHAD databases determine effects phase on growth. Using same hypotheses as Jackson Hunt theory, we find that law determined binary alloys in can be generalized systems with N elements. In particular, new model derived from this ternary eutectics. The predict microstructure discussed.
