Formation of high coercivity state in nanocrystalline FeCoCrB alloy
Source abstract
Abstract
The paper investigates changes in the magnetic properties of the amorphous Fe35Co35Cr14B16 alloy during isothermal crystallization. XRD, TEM, and EELS were used to study the evolution of the alloy structure during annealing and VSM was used to determine the effect of heat treatment on the magnetic properties. It is established that the hard magnetic state is achieved through spinodal decomposition in the bcc phase, forming an ordered FeCo B2 phase and a FeCr A2 phase, accompanied with Me2B and Me3B borides. The optimal annealing treatment leads to magnetic energy of the alloy is 9.25 kJ/m3, the saturation induction is 1.3 T, the coercive force is 22.7 kA/m.
