Analysis of the effects of alloying with Si and Cr on the properties of manganese austenite based on AB INITIO modelling

“…4, b). The theoretical hardness of manganese austenite, calculated from equation (5) (Fig. 4, d), correlates with the level of its stability and the nature of the formation of interatomic bonds (Fig.…”

“…In this case, it is especially important to assess the influence of dissolved alloying elements in manganese austenite on its stability and the physical-mechanical characteristics. In addition, when applying coatings from manganese steels, it is important to assess the effect of alloying on the thermophysical characteristics, which emerge in different procedures for calculating temperature fields [4,5]. Among these elements, it is important to assess the effects of silicon, which is part of almost all high manganese steels and coatings based on them.…”

Structural Construction of Binders Based on Orthophosphoric Acid and Refractory Materials

“…Single-layer and double-layer microarc oxide coatings are used as protective heat-resistant coatings on cores and molds [5][6][7][8]. During the research of casting processes, it is possible to apply modeling of thermal processes in layered structures, for example, temperature distribution in the mold and casting [9,10]. For the manufacture of molds and cores, the volume of which is millions of tons per year, we usually use iron phosphate and magnesium phosphate mixtures [4,[11][12][13][14], which often contain scarce and substandard components.…”

“…e ability to bind and stick by phosphates is associated with the crystalline structure, which is due to the position of phosphorus in the periodic table of elements [25]. Phosphate materials, including binders, have been widely used in many fields of technology [10,[26][27][28].…”

Influence of Plasma-Electrolytic Oxidation Process Technological Parameters of Aluminum on Coating Growth Rate

“…Для удосконалення конструкції бурового амортизатора застосовують циліндричні оболонки з розрізом [3]. Під час конструювання деталей та вузлів різного призначення застосовують силове та температурне моделювання взаємодії елементів [4][5][6], а також корозійні дослідження [7].…”
