RARE-EARTH HIGH ENTROPY ALLOYS AND TRANSITION METAL HIGH ENTROPY ALLOYS AS BUILDING BLOCKS FOR THE SYNTHESIS OF NEW MAGNETIC PHASES FOR PERMANENT MAGNETS

摘要

The invention relates to high entropy alloy of rare earth elements (RE-HEAs) including at least four and up to twelve elements selected form rare earth elements R₁,R₂,R₃,R₄,R₅,R₆,R₇,R₈,R₉,R₁₀,R₁₁,R₁₂, which rare earth elements R₁ to R₁₂ each represents one of elements 57 to 60, 62 to 70, 39 and 40 of the periodic system and to high entropy alloy of transition elements (TM-HEAs) including at least 3 and up to 12 elements selected from transitional elements TM₁,TM₂,TM₃,TM₄,TM₅,TM₆,TM₇,TM₈,TM₉,TM₁₀,TM₁₁,TM₁₂, which transitional elements TM₁ to TM₁₂ each represent at least one of elements 21 to 30, 41 to 48 and 72 to 79 of the periodic system. Such RE-HEAs and/or TM-HEAs can be used as building blocks in magnetic high entropy composite alloys, e.g. of the type (RE-HEAs)_x(TM-HEAs)_yT_z, for the manufacture of magnetic devices and permanent magnets.
