Relative effects of all chemical elements on the electrical conductivity of metal and alloys: An alternative to Norbury–Linde rule

“…2 (left plot) is inconsistent with that of Ref. [5], hence sulfur is classified as Class 2 instead of 1. In summary, the inputs for the model development consist of the variables defined in Eqs.…”

“…In addition, melting temperature has a strong correlation with the self-diffusion energy [17,18] that links to the mobility of the impurities and then the electron scattering. Furthermore, as stated by Norbury-Linde rule [5,6], the square of the difference in the atomic numbers between the impurity and the host metal is proportional to the resistivity, since atomic number is proportional to the attraction of nucleus to the valence electrons. Therefore, we select the above-mentioned five elemental properties in this study.…”

“…Increase in resistivity per addition of 1.0 atomic per cent added element (microhms per centimeter cube) (Source: Norbury [5] As shown in Fig. 4, the l P (Y axis) values due to R variations of 1% for samples of Class 1 are generally smaller than those of Class 2, which may indicate that pseudopotential radii R is an important factor in determining the electrical conductivity for Class 2 of which the impurities are transition metals and non-metals.…”

“…According to Nordheim's rule [3], the residual resistivity is proportional to impurity concentration. Norbury in 1921 also established an empirical rule [5] which states that the electrical resistivity of binary alloys at room temperature is further increased, as the position of a solute element (impurity) becomes distant from that of a host component in the periodic table of elements. This effect was later investigated by Linde who concluded that for a given quantity of impurity the residual resistivity is proportional to the square of the valence difference between the impurity and the host metal.…”

Manufacturing of Al-Zr Thermal-resistant Alloys for Transmission Lines

“…Table II presents the change in resistivity and IACS value of nearly pure aluminum and two dierent annealing type of Al-Zr alloy wires. The Northeim's rule is valid to appreciate resistivity behavior of materials [9]. It depends on the type and content of indredients that bases on the following formula:…”
