[12] In metallurgy, precipitation from a solid solution is also a way to strengthen alloys. Precipitation of ceramic phases in metallic alloys such as zirconium hydrides in zircaloy cladding of nuclear fuel pins can also render metallic alloys brittle and lead to their mechanical failure.
Wavelength- and subwavelength-scale particles, [5] metamaterials, [6] and other nanostructures [7] are not subject to ray-optical limits and may be designed to have an emissivity greater than 1. In national and international standards documents, the symbol M {\displaystyle M} is recommended to denote radiant exitance ; a superscript circle ...
