Equal Channel Angular Extrusion

In a land of metal and alloy, A technique was born, oh what a joy! Equal Channel Angular Extrusion, To create materials of fine resolution. Developed by Segal, a genius mind, In the Soviet Union, a treasure to find. With ECAE, metals are refined, Their strength and properties, oh how they shine! No reduction in cross-sectional space, A unique process, a magical embrace. Through channels and corners, the metal flows, Creating strains that only ECAE knows. Die design is key, for forces are great, To shape the metal, it must be straight. Lubricated with grease, the sample slides, Reducing friction, with each pass it glides. But at elevated temps, caution is due, Recrystallization, excessive grain growth too. Modifications exist, like I-ECAP, Continuous products, a new pathway. So let's celebrate this extrusion art, Where metals transform, a work of heart. ECAE, a magical creation, Bringing strength and beauty to every foundation. Random page: COBISS
