The soft magnetic properties of amorphous alloy toroids is improved by turning under tension an amorphous alloy ribbon onto itself to form a winding having a preselected number of turns such that the radially acting compressive stress is minimized. In one embodiment, the radially acting compressive stress is locally minimized by using such a toroid pole-piece geometry that the windings have as little an area of curvature as is possible. In another embodiment, the radially acting compressive stress is globally minimized by turning the ribbon onto itself such that successive turns of the winding are wrapped with progressively less tension.

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.

Zirconium-base alloy structural component for nuclear reactor and method

A fast neutron-irradiated zirconium-base alloy body having load-carrying capacity substantially greater than similar conventional zirconium-base alloy bodies likewise irradiated is produced by subjecting a body heat treated at 930.degree. C. and then water-quenched and containing 0.2 weight percent beryllium and at least 95 weight percent zirconium to integrated neutron flux approximating 1.2.times.10.sup.21 nvt while maintaining the body at about 330.degree. C.
