主 题:amorphous alloy atomic diffusion SIMS Fe_(78)Si_9B_(13) diffusivity
摘 要:Ion beam sputtering profiling in combination with SIMS technique was employed to investigate the Al diffusion in Fe_(78)Si_0B_(13)amorphous *** 320 and 380℃,the diffusion coefficients vary from 2.43×10^(-22) to 2.01×10^(-21)m^2s^(-1),and an Arrhenius relationship was established as:D_0=2.02×10~_(12)exp(-1.17/kT)
