Plunge milling is an efficient machining process for roughing deep pockets. Its efficiency is mainly due to low radial forces on the cutter. This leads to reduced bendings and vibrations that allow one to improve cutting parameter values. The machining time can then be reduced with respect to machining processes with constant Z-level. Recently, another …

Rare earth elements are often added to chromium dioxide forming alloys to improve its high temperature oxidation resistance. The rare earths can be also added as oxide dispersions. Significant cost reductions are possible if rare earth oxide concentrates can be used instead of pure rare earth oxides, the former being the precursor to obtaining pure rare earth oxide.
