✦ Synopsis

The high-fluence irradiation-induced dimensional changes of co-deposited carbon-silicon alloys have been investigated at several temperatures. The silicon, which is generally incorporated as silicon carbide, an irradiation-stable phase, leads to reduced density and dimensional changes if sufficient silicon carbide is present. The density of the carbon phase tends to decrease with increasing silicon carbide content and is also an important variable. For silicon carbide fractions above about 0.3 and carbon densities below about 1.9 g/cm3, the dimensional changes do not depend strongly on the irradiation temperature and are considerably smaller than those of unalloyed carbons.
