PENGARUH ARAH PENGEROLAN DAN SHEAR CUTTING TERHADAP KARAKTER PADUAN AlMg2 SEBAGAI MATERIAL CLADDING BAHAN BAKAR REAKTOR RISET

Abstract

THE INFLUENCE OF ROLLING DIRECTION AND SHEAR CUTTING ON THE CHARACTERISTICS OF AlMg2 AS FUEL CLADDING MATERIAL FOR RESEARCH REACTOR FUEL. Gradual rolling process of AlMg2 alloy has been carried out to obtain a certain thickness with final mechanical behavior suitable for fuel cladding of research reactor. The post-irradiation testing of fuel element used mini specimens to minimize radioactive waste. The purpose of this study was to study the influence of rolling direction and shear cutting on AlMg2 alloy characteristics. The tests performed include tensile, metalographic and hardness tests after rolling. The results show that AlMg2 alloy rolled by same direction has lower tensile strength and hardness and is more ductile than that rolled by transverse direction. The structure of AlMg2 alloy after hot rolling consists of  (Al) phase with precipitates distributed along the elongated grains in the rolling direction. Shear cutting affects the width and hardness of the deformation area on the cut surface of the specimens.
