摘要
本文建立了通过脱硼处理用径迹显微照相技术测量硼在合金中扩散系数的新方法。该法灵敏度高,简捷可靠。实验发现,Ni中加入0.5％Mo对硼的扩散影响不大;而加入3％Mo则有使硼的矿散激活能降低,频率因子减小,在900—1250℃的温度范围内有加快硼扩散的作用。
A new technique for the measurement of B diffusivity in B bearing alloys by particle tracking autoradiography after deboronization has been established with high sensitivity, good reprocibility and fair simplicity. Experimental results show that the Mo addition up to 3％ into Ni may accelerate the B diffusion in the range of 900—1250℃ and reduce both the activation energy and the frequency factor, of B diffusion but no more influential as the Mo added down to 0.5％.
