摘要
A tubing comprising a zircalloy 2 casing with an internal zirconium coating is produced by water quenching a worked zircalloy 2 bar from the beta range before or after cutting into billets which may be pierced or not followed by a possible anneal. Water quenching a worked non-alloy zirconium billet containing 250-1000 ppm Fe, before or after piercing from 880-1050 degrees C followed by extruding in the alpha range. The zirconium tube is positioned inside the zircalloy billet and the assembly extruded in the alpha range followed by cold rolling and heat treatment. The complete thermomechanical treatment is such that the size of the gains in the zircalloy and zirconium layers is respectively 9-12 and 6-10 ASTM with at least is difference of 2 ASTM being present.
