This polycrystalline structure that underlies what we call a Schwarz crystal is stable against grain coarsening, … WebNov 1, 2024 · Abstract. Metals usually exist in the form of polycrystalline solids, which are thermodynamically unstable because of the presence of disordered grain boundaries. Grain boundaries tend to be eliminated through coarsening when heated or by transforming into metastable amorphous states when the grains are small enough.
WebApr 6, 2024 · The strength and toughness of materials are important for applications. A linear atomic chain, carbyne, has been previously predicted to have the highest strength and toughness. WebWe propose a spectral viewpoint for grain boundaries that are generally quasiperiodic. To accurately capture the spectra computationally, it is crucial to adopt the projection method for quasiperiodic functions. Armed with the Lifshitz--Petrich free energy, we take the spectral viewpoint to examine tilt grain boundaries of the hexagonal phase. Several ingredients of …
