Polycrystalline materials result when a substance solidifies rapidly; crystallization commences at many sites (see nucleation), and the structurally ordered regions growing from each site …

Not all solids are single crystals. When a metal starts with crystallization, the phase change begins with small crystals that grow until they fuse, forming a polycrystalline structure.

Polycrystalline materials are defined as solids composed of many single-crystal regions, known as grains, which exhibit long-range order. These grains may have random orientations relative to …

A polycrystalline structure is a solid material composed of many microscopic crystals, known as crystallites or grains, which have varied sizes and orientations. Most common metals, many …

Single crystals form only in special conditions. The normal solid form of an element or compound is polycrystalline. As the name suggests, a polycrystalline solid or polycrystal is made up of …

Polycrystalline refers to a material that is made up of multiple single crystals with varying sizes, shapes, and orientations. These materials are composed of single-crystal grains that can be …

Polycrystalline materials can be defined as the counterpart of single crystals. These latter arise from solution crystallization by transfer of a solute from the liquid phase to the crystalline phase.

On the other hand, polycrystalline materials consist of multiple small crystals or grains, each with their own crystal lattice orientation. This random arrangement leads to a less uniform structure …

Polycrystalline materials are a class of solids composed of numerous crystallites, also known as grains, which are randomly oriented and separated by grain boundaries.
