Effect of Pre-Annealing Time on Crystallization of Sm2Fe17ZrNb0.4Cu0.2B0.2 Amorphous Alloy AITranslate
Abstract AITranslate
Sm2Fe17ZrNb0.4Cu0.2B0.2amorphous alloy ribbons were prepared by fast quenching at the speed of 40 m/s in a high vacuum arc melting and single-roll rotary quenching integrated furnace.In order to realize the explosive nucleation of amorphous alloy ribbons at relatively low crystallization temperature,and refine grains and together improve the uniformity of microstructure,it is necessary to improve the order degree of atoms before crystallization.Therefore,the amorphous alloy ribbons were pre-annealed at 500℃for different time to study the crystallization evolution of the amorphous alloy with different pre-annealing time.The results analyzed by X-ray diffractometer(XRD)and high-resolution transmission microscope(HRTEM)show that long-term pre-annealing treatment has a great influence on the precipitation ofα-Fe phase.When the pre-annealing temperature is 500°C,the pre-annealing time should not exceed 90 min.Too long pre-annealing time leads to the early precipitation of crystal phase and uneven crystallization microstructure.
