| Abstract | ||
| Been studied the influence of temperature on the electrical conductivity properties of the alloy samples Fe0.70-xVxAl0.30 manner, and processed electric arc furnaces, which enters as an additive component vanadium concentration of extenuating equal to (0.02 and 0.06 and 0.10 and 0.20 and 0.30) in the Over the temperature was 300K to 500K to calculate the values of activation energy and determine the type of electric charge carriers. The measurements showed that the connectivity of the samples increases electrical conductivity, up from both the temperature and the concentration of vanadium element in the alloy, it was noted that the energies of these samples in the revitalization of different values, which indicates the existence of different mechanisms for the delivery of which was becoming increasing temperature and values less than the values of the energy gap, shown the results of the measurements that the electrons are the majority of the positive electric load in the samples. | ||
