1. the fine structure of a material, visible only under a microscope, consisting of crystals, grains, and phases that determine the material's properties
Usage: technical; materials science
2. the small-scale organizational pattern or arrangement of components within a system or substance
Usage: general usage

Examples

• The microstructure of the steel sample revealed a mixture of ferrite and cementite phases.
• Engineers examined the microstructure under an electron microscope to understand why the material failed.
• Heat treatment changes the microstructure of metals, affecting their strength and flexibility.
• The microstructure of the alloy determines its hardness and corrosion resistance.
• Researchers studied the microstructure of the ceramic to improve its thermal properties.
• The fine microstructure of the composite material gives it superior performance.
