ABSTRACT:
A small amount of lanthanum and praseodymium will substantially improve the slow strain rate ductility of certain zirconium-base alloys and these new alloys and certain other zirconium-base alloys in the irradiated condition can under certain circumstances have surprising load-carrying capacity and service life. Such other alloys contain yttrium or calcium instead of lanthanum or praseodymium.
