Specific features of electrical properties of the In<Subscript>x</Subscript>Ga<Subscript>1 − <Emphasis Type="Italic">x</Emphasis></Subscript>N alloy

Temperature dependences of the Hall coefficient and resistivity of the In_xGa_{1 ? x} N alloys (0 ≤ x ≤ 1) are investigated. It is found that, at x ≤ 0.4, the temperature dependences of the Hall coefficient and resistivity have the activation-related portion. The activation energy depends linearly on the In content in the alloy. At x ≈0.5, the activation portion vanishes. The main scattering mechanism depends on the temperature, on the defect density in the film (this density is largely determined by the used intermediate GaN layers), and on the alloy composition x.

Quality of thick steel sheet for spiral-seam electrowelded pipe of strength class K60 (X70)

The mechanical properties, microstructure, fractures, and texture of a trial industrial batch of 07Г2MФБ steel sheet (thickness 21.7 mm) for the manufacture of spiral-seam gas-line pipe (diameter 1420 mm) of strength class X70 at OAO Volzhskii Trubnyi Zavod (VTZ) are investigated. It is shown that the selected chemical composition of the steel and thermomechanical rolling technology yield mechanical properties of the sheet and the basic pipe metal complying with VTZ specifications.
