What Does ECAE Stand For?

ECAE stands for Equal Channel Angular Extrusion

ECAE, or Equal Channel Angular Extrusion, is a manufacturing process used to refine the microstructure of metals and alloys. It involves the severe plastic deformation of materials by forcing them through a die with two channels of equal cross-section that intersect at an angle. This technique enhances mechanical properties, such as strength and ductility, by promoting uniform grain distribution without changing the material's cross-sectional area. ECAE is particularly useful in producing ultra-fine grained materials for various applications in automotive, aerospace, and structural engineering.
