Novel cobalt-free iron-base, wear-resistant and anti-galling, hardfacing alloys are provided. These alloys are capable of being deposited on substrates by welding without preheating the substrate, thus facilitating field applications of cobalt-free alloys.

Cobalt-free hardfacing alloys with improved welding characteristics

Novel wear-resistant, anti-galling, cobalt-free hardfacing iron based alloys are provided which are useful for construction of plant or manufacturing facility components exposed to aggressive environments. The alloys are particularly useful to construct components used in the cooling systems of nuclear power plants.

Cobalt-free, iron-base hardfacing alloys

A fuel pellet comprised of an inner cylindrical part provided with a mixture of uranium oxide and plutonium oxide, and an outer annular part integral with the inner part and containing uranium oxide free of plutonium oxide. The fuel pellet is adapted to be inserted into a fuel rod with other such pellets in end-to-end relationship. The pellet is formed by cold pressing the uranium oxide and plutonium oxide in respective inner and outer parts, then sintering the parts to form a monolithic body with the two parts integral with each other.
