EUROINVENT 2012
selection of alloy composition and production process
parameters to obtain hard magnetic materials with unique
nanostructure. Obtained TbCu7 type of structure is
characterized by stable or abnormal (positive) coercivity
and remanence parameters in wide temperature range. The
production of such materials is extremely hard due to
metastable character of desired crystalline phase. Projects
related with described functional materials are counted to
the so called “cutting edge” topics in manufacturing
magnetic materials. Summarizing, due to unique thermomagnetic
properties these materials are extremely
interesting for companies prducing high temperature
sensors and motors working in harsh conditions.
