This article is devoted to the development of a methodology for calculating the hydrodynamic characteristics of liquids boiling in mini-channels. In contrast to the well-known methods, the proposed methodology is based on the use of the true volumetric steam content and prediction of two-phase flow regimes in the field of a steady flow. The article presents experimental data on the true volumetric steam content, pressure loss, and two-phase flow pattern in mini-channels

The article presents evidence proving that the alloys of the CuZnAl system, unlike the CuAl (Ni, Mn) system, have a smaller contact area with the quenching disk. It is caused by the condensation of Zinc vapors from the melt on its quenching surface. In addition, it is shown that Bronze alloys, in comparison with Brasses, are preferable for obtaining tapes by spinning. The main patterns of changes in critical points and the value of the Shape Memory Effect (εSME), depending on the types of heat treatment are also analyzed in this paper. Exposure of the alloy to the mold setting temperature of T = 800÷850 °C is accompanied by grain growth, increase in critical points, and decrease in the value of Shape Memory Effect. In this regard, the holding time at the mold setting temperature should not exceed t = 3÷5 min.
