摘要：
Desorption behavior of oxygen from grain boundaries vacuum annealing at temperatures between 1423 and 1743 K was studied by Auger electron spectroscopy. The grain boundary diffusivity of oxygen is D (m**2/s) equals 7. 8 multiplied by 10** minus **3 exp left brace minus (270kJ/mol)/RT right brace . Ductility at room temperature was improved when the oxygen concentration in grain boundaries was reduced to around 1 at%.
