Here, we present a systematic study on the formation mechanism of 2D polycrystals. Based on the alignments of 2D single crystals on a substrate and phase PFT simulations, a general strategy of ...

Anisotropy in single-crystal properties of polycrystals controls both the overall response of the aggregates and patterning of local stress/strain distributions, the extremes of which govern failure ...

Most crystalline materials are polycrystals, such as metals. They are composed of many small crystalline grains with different lattice orientations. The interface between two crystalline grains, i.e., ...

Polycrystals are solid materials that are made up of lots of small crystals. The points where the crystals meet are known as grain boundaries (GBs). GBs are important because they can affect the way ...
