Local distortions, insulating regions, and nature of the high-resistance state in titanium- and zirconium-based metastable alloys
Katsnel'son M. I., Trefilov A. V.
A quantum size effect is hypothesized in the electron spectrum in disperse particles of an ω phase, on the basis of an analysis of features of the structural state of the lattice of metastable titanium and zirconium alloys and the electronic structure of the ω phase. Analysis of the scattering of "external" electrons by such regions leads to an understanding of the basic reasons for the formation of the high-resistance state in these alloys. Resistive anomalies and structural anomalies (local distortions) in dilute alloys are explained under the assumption that small quasicrystalline (icosahedral) clusters form.
