Structural State and Magnetic Properties of Nd2Fe14B-Type Rapidly Quenched Alloys
Using the X-ray, elastic neutron diffraction (END) and small angular neutron scattering (SANS) methods (Dif-fractometers D2 and D3 respectively), transmitting electronic microscopy (JEOL JEM-200CX) and magnetometry technique (vibrating sample magnetometer -VSM) the structure and magnetic properties of the rapidly quenched (RQ) alloys of the following compositions: A) Nd14Fe78B8; B) Y12Fe82B6; C) Nd13.3Co6.6Fe72.6Ge0.9B6.6; D)Nd9Fe85B6; E) Nd9Fe79; F) Nd9Fe74Ti4CB12 have been studied. At some quenching conditions or after consequent heat treatments of these alloys the nanoscale state of the main 2-14-1 phase and α-Fe grains can be formed. Their size depends on the sample-preparation conditions and lies in the interval of 10-200 nm. Their influence on magnetic properties of alloys under study is discussed.
