抄録

The effective valences Z^∗ and the non-dimensional number δ of carbon and nitrogen in γ-iron for the solid state electrotransport have been measured by the tangent method under the following conditions: electric field intensity=3.0-11.3 V·m⁻¹, temperature=1223-1323 K, initial carbon content=0.1-0.9 mass% and nitrogen content=0.025 mass%. The influences of these factors on Z^* and δ were examined, and the following results were obtained:<BR>(i) At the electric field intensity below 5.0 Vm⁻¹, Z^∗ of carbon increased rapidly with decreasing electric field intensity, but δ kept constant. Above that value, Z^∗ of carbon was constant, and δ increased linearly with increasing electric field intensity.<BR>(ii) Temperature did not influence Z^∗ and δ of carbon under the present experimental conditions.<BR>(iii) Z^∗ and δ of carbon decreased gradually with increasing concentration of carbon.<BR>(iv) Z^∗ of carbon and nitrogen increased slightly when both elements coexisted.
