PRODUCTION OF TUNGSTEN ALLOY PENETRATION RADIATION SHIELDS *

Abstract

Manufacturing procedures are Manufacturing procedures are given for a series of high-density sintered tungsten-nickel-copper and tungsten-nickel-iron alloys covering a density range of ∼17 g/cm³ to > 18·5 g/cm³.

Physical and mechanical property data for these alloys are given and the effect of sintering variables on these properties is discussed.

Reference is made to equipment and techniques employed in the manufacture of radiation shields to meet the most stringent demands brought about over the years by the increased strength of radiation sources and the widening scope for the application of artificial radioactive elements.
