New Publication in “Physical Review B”

We construct the atomistic spin model Hamiltonian for Nd2Fe14B by using the Heisenberg exchange of Fe−Fe and Fe−Nd atomic pairs, the uniaxial single-ion anisotropy of Fe atoms, and the crystal-field energy of Nd ions, which is approximately expanded into an energy formula featured by second-, fourth-, and sixth-order phenomenological anisotropy constants. …

New Publication in “ACS Applied Nano Materials”

In this article, we explore the corrosion resistance afforded to aluminum alloy AA7075 substrates by unfunctionalized exfoliated graphite nanocomposite coatings as a function of the exfoliated graphite loading. …

Congradulation and farewell for Dr. Min Yi and his future career as a professor under the Thousand Youth Talents Program in Nanjing University of Aeronautics and Astronautics (NUAA). …

Upcoming Work

In this work, a non-isothermal phase-field model is developed based on the entropy analysis, which includes contributions from the internal energy (induced by the change of temperature and order parameters) and the order parameter related configurational entropy. It is anticipated that the work could provide a contribution to the research community of unconventional sintering techniques that can be used to model the non-isothermal related microstructural features. …

New Publication in “Computational Mechanics”

In this work, we will present the first attempt to computationally study the microstructure evolution and magnetic properties of magnetic materials (e.g. Fe–Ni alloys) processed by selective laser melting (SLM). The evolution and distribution of the γ -Fe–Ni and FeNi3 phase fractions are predicted by using the temperature information from FEA and the output from CALculation of PHAse Diagrams (CALPHAD).

New Publication in “Journal of Power Sources”

In this work, we propose a two-level framework, which extends the P2D cell model and incorporates a mechanically coupled phase-field Cahn–Hilliard diffusion model of active particles. …

Bai-Xiang Xu and Marc-André Keip are organizing the Mini-Symposia entitled “MS22: Recent Trends in Phase-Field Modeling: Theory, Numerics, Applications” in 8th GACM Colloquium on Computational Mechanics (GACM 2019) in Kassel on Aug. 28th-30th.

We congratulate our colleague Shuai Wang to the successful dissertation of his PhD thesis “Phase-Field Modeling of Relaxor Ferroelectrics and Related Composite”.

New Publication in “Journal of Power Sources”

Investigations on the fast capacity loss of Lithium-ion batteries (LIBs) have highlighted a rich field of mechanical phenomena occurring during charging/discharging cycles, to name only a few, large deformations coupled with nonlinear elasticity, plastification, fracture, anisotropy, structural instability, and phase separation phenomena. …

New Publication in “Advanced Electronic Materials”

Here, we direct investigate different coupling effect by introducing soft and charge interphase layers in the serial‐type layer composite model. A new relaxor phase‐field model is first developed to reproduce this phase transition and parameterized by fitting the measured hysteresis loops. …
