TRIP-assisted CMnSiAl steels with a fully martensitic initial microstructure have been studied in order to investigate the effect of partial substitution Si by Al. The steel was fabricated casting sand mold, hot forged, homogenizing, rolling, cold intercritical annealing, and finally, an isothermal bainitic treatment. During annealing at 1023 K (750 °C) for 420 s, matrix consisting 50% proeutec...

Ti0.33Al0.67)1-xSixN (0≤x≤0.29) thin solid films were deposited onto cemented carbide substrates by arc evaporation and analyzed using analytical electron microscopy, X-ray diffraction, nanoindentation, and density functional theory. As-deposited films with x≤0.02 consisted mainly of a metastable c-(Ti,Al)N solid solution for which Si serves as a veritable grain refiner. Additional Si promoted ...

We followed the first stages of liquid–liquid phase separation in an alkali-borosilicate glass by complex impedance spectroscopy at constant temperatures below and above the glass transition temperature, Tg. We found a new feature of the electrical conductivity behavior: at temperatures below Tg, the electrical conductivity, r, diminished with time, while above Tg, the electrical conductivity i...

Thin metal films are used in semiconductor and microelectronic devices to form ohmic non-ohmic contacts singlecrystal silicon. A common feature of the Ме–Si systems is low mutual solubility elements polycrystalline nature films. Solid-phase interactions during deposition metals on single-crystal silicon subsequent vacuum annealing results redistribution near Me/Si interface. An important task f...

The present article serves the purpose of pursuing Geometrization of heat flow on volumetrically isothermal manifold by means of RF approach. In this article, we have analyzed the evolution of heat equation in a 3-dimensional smooth isothermal manifold bearing characteristics of Riemannian manifold and fundamental properties of thermodynamic systems. By making use of the notions of various curva...

Pressed strontium ferromolybdate (Sr2FeMoO6−δ) pellets with different oxygen indices δ and degrees of superstructural ordering (SO) are synthesized by solid-phase citrate-gel methods to study magnetic electric transport behaviors this compound. The crystalline structure the samples is found demonstrate Fe Mo cations, which increases increase in δ. saturation magnetization Curie temperature corr...
