The magnetic field dependences of the magnetization (B≤9 T, T=2-70 K) samples from a single crystal Pb 1-y Sc y Te (y=0.01) ingot, synthesized by Bridgman method, are studied. It is established that, in accordance with generally accepted model rearrangement electronic structure alloys during doping, there no paramagnetic contribution scandium ions located nodes metal sublattice studied samples....

The non-oriented Fe-6.5wt.%Si alloy cast strip with a width of 100 mm and thickness 1.7 was prepared by the top side-pouring twin-roll-casting (TSTRC) process. surface quality air-cooled water-cooled good. Compared ingot, has fine solidification structure exhibits certain plasticity at room temperature. Microhardness, XRD, TEM investigated ordered degree alloys three different cooling methods. ...

This paper presents an experimental validation of in situ ultrasound technique for tracking the solid–liquid interface during directional solidification photovoltaic silicon. Ultrasound bursts are introduced from top into melt via tip a carbon glass waveguide directly plunged liquid. Several runs have been conducted using same thus demonstrating its reusability, mechanical resilience and approp...
