Nearly all metals, alloys, ceramics, and their associated composites are polycrystalline in
nature, with grain boundaries that separate well-defined crystalline regions that influence …

Grain boundary segregation is one of the crucial phenomena affecting the properties of the
materials and their technological applications. However, 50 years since starting its intensive …

Hydrogen embrittlement caused by hydrogen segregation at grain boundaries (GBs) is the
most serious issue in the development of high-strength steels, but the mechanisms behind …

Atomistically-informed phase field simulations have been performed to investigate the effect
of five common alloying elements (Nb, Ti, Mo, V, Mn) on austenite grain growth. The …

The segregation of solute elements to defects in metals plays a fundamental role for
microstructure evolution and the material performance. However, the available …

Solute segregation is a crucial means of stabilizing nanostructured alloys, and at very small
grain sizes, this requires consideration of triple junctions (TJs), which attain a meaningful …

Diffusion plays a vital role in regulating microstructure evolution and properties of metallic
materials. However, understandings of how microalloying affects diffusion kinetics in gold …

Conventional grain growth models do not account for the variability in grain boundary (GB)
mobility, GB energy, and solute segregation energy that depend in detail on the GB …

The austenite-ferrite transformation is the key metallurgical tool to tailor properties of low
alloyed steels and remains an active area of research. Models have yet to be developed …

In Part I of this work, we proposed a stochastic model describing solute interactions with
stationary and moving grain boundaries (GBs) and applied it to planar GBs in 1D systems …
