HIGH INTENSITY ZIRCONIUM ALLOY CONTAINING BISMUTH, TIN AND NIOBIUM

摘要

PURPOSE: The present invention is provided to high intensity zirconium alloy improved intensity and anticreep meanwhile having high intensity rather than zircaloy-2 or zircaloy-4 using new alloy for inside of cladding to maintain low parasitic neutron. CONSTITUTION: High intensity zirconium alloy consisted of bismuth from 1.5 to 6 weight%, tin from 1 to 4 weight%, niobium from 0.5 to 3 weight% and the rest of zirconium.
