THE INFLUENCE OF EXPOSURE TO THERMAL NEUTRONS ON SEVERAL PROPERTIES OF HEAT-RESISTANT SITALLS,

Abstract

This is a report on the first attempts to determine the effects of radiation on various pyrocerams, including heat-resistant. Samples, enclosed in aluminum containers, were subjected to neutron bombardment in varying doses within experimental channels of nuclear reactors at no more than 40C. Observed changes in micro-hardness had different characteristics for small and for large doses. These changes and changes in other parameters measured (density, mechanical strength, dielectric properties, coefficient of thermal expansion, and phase composition) often exhibit extrema at doses which depend on the composition of the material.
