摘要：
The diffusion of nitrogen in alpha-Hf was studied in the temperature range of (823-1123) K using the ion implantation and nuclear resonance techniques. The measurements show that the diffusion coefficients follow the Arrhenius behavior D(T)=D (0)exp (-Q/RT) with D (0)=(5.5 +/- 2.1)x10(-7) m(2)/s and Q=(228 +/- 1) kJ/mol. A comparison of the present results with the previous one is done.
