Electrical Resistance of Alloys

Corrosion Resistance of Dental Alloys

Metals and metallic alloys are unavoidable materials in everyday dental use for the making of fillings, cast cores and post systems, individual crowns, implantants’ suprastructures, dentures and orthodontic devices. They still belong to the vital materials in dentistry. Applied alloys in a mouth are exposed to the influence of chemical, biological, mechanical, thermal and electrical forces whic...

Oxidation Resistance of Nanocrystalline Alloys

Electrical Resistivity of Liquid Alkali Na-based Binary Alloys

The study of the electrical resistivity ρL of alkali Na-based binary alloys Na1−xLix, Na1−xKx, Na1−xRbx and Na1−xCsx have been made by well-recognized model potential of Gajjar et al. The most recent exchange and correlation functions due to Farid et al (F) and Sarkar et al (S) are used for the first time in the study of electrical resistivity of liquid binary mixtures and found suitable for su...

Electrical resistivity of ferromagnetic nickel and iron based alloys

We discuss in detail the theoretical basis for the two-band model with spinmixing which has been widely applied to the analysis of the transport properties of ferromagnetic metals. This model is shown to have much more general validity than the original presentation suggested. The model is then applied to resistivity data in Ni and Fe based alloys to obtain a consistent set of parameters for th...

Magnetostriction and electrical resistivity of Mn doped Fe81Ga19 alloys

The paper reports on the effect of substituting Mn for Fe on the magnetostrictive and related properties of Fe81−xMnxGa19 alloys. Samples of composition were prepared in polycrystalline form and were all single phase BCC. It is shown that the magnetostriction observed in Fe81Ga19 can be enhanced up to about 11% by Mn substitution with a maximum effect at x = 8. The change in the magnetostrictiv...
