Grain Boundary
A grain boundary is where different crystal structures meet in metals and materials - think of it like the borders between countries on a map, but at a microscopic level. This is important because these 'borders' affect how strong, durable, or resistant to corrosion a material will be. When candidates mention grain boundary experience, they're typically talking about their ability to analyze and improve material properties in metals, ceramics, or other industrial materials. This knowledge is crucial for roles in manufacturing, quality control, and materials development.
