Grain Boundary Engineering

Grain Boundary Engineering is a process used to improve materials like metals and alloys by modifying their internal structure. Metals are made up of tiny, crystalline regions called grains, separated by boundaries. The properties of the material, such as strength and corrosion resistance, are influenced by these boundaries. By controlling the arrangement and characteristics of grain boundaries—such as making them more resistant to cracking or corrosion—engineers can enhance the material’s performance and durability. This technique is essential in industries like aerospace, automotive, and power generation, where materials need to withstand demanding conditions.
