摘要
The law and activation energy of annealing embrittlement for three kinds of popular Fe B Si amorphous alloys have been studied. For comparison, the crystallization activation energy (CAE) of these alloys was measured by XRD equal first peak height method and conventional Kissinger method. The structural relaxation activation energy (SRAE) of these alloys was measured by Curie temperature method or internal friction method. Through the comparison and analysis of the activation energies of annealing embrittlement, crystallization and structural relaxation, the related influencing factors on annealing embrittlement of Fe based amorphous alloys are elucidated.
