Heat Treatment of a Melt Spun FE70CR18MO2B10 Alloy

摘要

Microstructural changes during annealing of melt spun Fe70Cr18Mo2B10 ribbons werestudied by a combination of differential scanning calorimetry, X-ray diffractometry, transmission electron microscopy, and energy dispersive X-ray microanalysis. The as-melt spun microstructure consists of bcc ferrite primary crystals embedded in an amorphous matrix. The crystallization onset, peak and finish temperatures of the amorphous phase are 533, 552, and 573 C, respectively, during continuous heating at 10 C/min. Isothermal annealing of the as-solidified
