A Scale-Separated Full-Field Monopole Method for Precipitation Modelling
C. W. Sinclair
A scale-separated monopole method is developed for full-field prediction of precipitation under conditions where particle-scale diffusion fields coexist with solute variations over…
Predicting the effect of strain path on the strain aging behaviour of Ultra-low carbon steel
Wendel A. Melo, Chad W. Sinclair
A recently presented model is adapted to predict the effects of strain path change on the strain aging (bake hardening) behaviour of an ultra low carbon (ULC) steel. Samples pre-de…
Vibratory Powder Feeding for Powder Bed AdditiveManufacturing using Water and Gas Atomized MetalPowders
C. W. Sinclair, R. Edinger, W. Sparling +2
Commercial powder bed fusion additive manufacturing systems use recoaters for the layer-by-layer distribution of powder. Despite the known limitations of recoaters, there has been…
Modelling the relationship between deformed microstructures and static recrystallization textures: application to ferritic stainless steels
Arthur Després, Jean-Denis Mithieux, Chad. W. Sinclair
We present an original approach for predicting the static recrystallization texture development during annealing of deformed crystalline materials. The microstructure is considered…
The Benefits of Trace Cu in Wrought Al-Mg Alloys
S. Medrano, H. Zhao, B. Gault +2
The softening and strengthening contributions in pre-deformed and aged Al-Mg-Cu alloys containing 3wt.%Mg and 0.5wt.%Cu are evaluated by a combination of microscopy, mechanical tes…
Carbon Diffusion in Concentrated Fe-C Glasses
Siavash Soltani, Joerg Rottler, Chad W. Sinclair
By combining atomistic simulations with a detailed analysis of individual atomic hops, we show that the diffusion of carbon in a binary Fe-C glass exhibits strong (anti-)correlatio…
A mean-field model of static recrystallization considering orientation spreads and their time-evolution
Arthur Després, Michael Greenwood, Chad Sinclair
In this paper, we develop a mean-field model for simulating the microstructure evolution of crystalline materials during static recrystallization. The model considers a population…
Controlling solid-liquid interfacial energy anisotropy through the isotropic liquid
Lei Wang, Jeff Hoyt, Nan Wang +2
Although the anisotropy of the solid-liquid interfacial free energy for most alloy systems is very small, it plays a crucial role in the growth rate, morphology and crystallographi…
An Atomistic Study of Diffusion-Mediated Plasticity and Creep using Phase Field Crystal Methods
Joel Berry, Jörg Rottler, Chad W. Sinclair +1
The nonequilibrium dynamics of diffusion-mediated plasticity and creep in materials subjected to constant load at high homologous temperatures is studied atomistically using Phase…
Phase Field Crystal Modeling as a Unified Atomistic Approach to Defect Dynamics
Joel Berry, Nikolas Provatas, Jörg Rottler +1
Material properties controlled by evolving defect structures, such as mechanical response, often involve processes spanning many length and time scales which cannot be modeled usin…
A three-dimensional atomistic kinetic Monte Carlo study of dynamic solute-interface interaction
Aulia Tegar Wicaksono, Chad W. Sinclair, Matthias Militzer
A three-dimensional atomistic Kinetic Monte Carlo model was developed and used to study the interaction between mobile solutes and a migrating interface. While the model was develo…
Defect stability in phase-field crystal models: Stacking faults and partial dislocations
Joel Berry, Nikolas Provatas, Jörg Rottler +1
The primary factors controlling defect stability in phase-field crystal (PFC) models are examined, with illustrative examples involving several existing variations of the model. Gu…
