1. The small-scale internal structure of a material, visible only under a microscope, consisting of grains, phases, and defects.
Usage: Plural form of microstructure.; Commonly used in materials science, metallurgy, and engineering.

Examples

• The microstructures of the steel sample were examined under an electron microscope.
• Different heat treatments produce different microstructures in the alloy.
• Engineers study microstructures to understand how materials will perform under stress.
• The microstructures of ceramics affect their strength and brittleness.
• Advanced imaging techniques reveal the complex microstructures of composite materials.
• Controlling microstructures during manufacturing is essential for product quality.
