What Does FGHAZ Stand For?

FGHAZ stands for Fine Grain Heat Affected Zone

FGHAZ, or Fine Grain Heat Affected Zone, refers to a region in a material, typically metal, that experiences microstructural changes due to thermal effects during welding or other high-temperature processes. This zone is characterized by fine grain structures that can influence the mechanical properties, such as strength and toughness, of the material. Understanding FGHAZ is crucial in assessing weld integrity and overall performance in engineering applications.
