Improvement of the chemical composition and structure of castable nickel-base superalloy with low density. Part 1

The tendencies of advancement of nickel-based superalloys for casting blades of aircraft engines are considered. The durability of polycrystalline heat-resistant Nickel alloys of the VZhL12U type with variable content of alloying elements W, Mo, Cr, Co, Ti, Nb, Hf, and C at temperature 975 °C and stress 200 MPa was studied using the method of mathematical planning of the experiment. Based on the results of the research, concentration regression models of durability were constructed and the effect of Hf on the temperatures γ'-solvus, melting γ+γ' eutectic, solidus and liquidus of VZhL12U-type alloys was established.

Intermetallic compound AlxTi – are promising material for high elevated temperatures (review) Part 1. The crystaline structure and properties of the intermetallic compound Al2Ti

The Al2Ti intermetallic compound is the most promising base for high-temperature alloys designed for advanced power plants. This work provides an overview of the structures of binary alloys concerning to the Ti–Al system, as well as the phase transformation mechanisms and the peculiarities of plastic deformation of alloys. The alloys which phase composition is represented by a mixture of r-Al2Ti+γ-TiAl with a lamellar structure show anomalous mechanical properties depending on texture formation and grain size. These alloys possess increased strength and decreased plasticity at elevated temperatures.

FDM-printed functional materials (review)

The paper provides an overview of studies carried out in the field of obtaining functional materials the FDM printing method. Data on the influence of the type of polymer matrix, filler composition, and FDM printing technological modes on the functional and physical-mechanical properties of composites are presented. It is shown that the technology of layer-by-layer hot-melt printing makes it possible to obtain polymeric materials with electrical conductivity from 10-2 to 1.4·105 S/m, to increase the thermal conductivity to 0.9 W/(m∙K), and to manufacture magnetoplastics. It is noted that to obtain a high level of functional properties, it is required to use polymer matrices with a degree of filling of 5–75 wt %, which inevitably leads to a significant change in the physical and mechanical properties and heat resistance of the material. Possible directions for further research in this area are indicated.

Robotic laying out of prepregs as an alternative to technology to ATL and AFP (review)

With the growing use of composite materials, the automated production of parts using prepreg is gaining increasing interest. There are two main types of prepreg laying automation: Automated Tape Laying (ATL) and Automated Fiber placement (AFP). Both of these technologies are not always cost effective for all types of parts, and manual labor tends to be used to make complex parts with low production volumes. As an alternative to these two dominant automation solutions, there are 4 options for automated laying with manipulators.

The influences of manufacturing technology of the magnetron targets on the microstructure and phase composition of Zr–Y-based alloy

The Zr–Y-based alloy targets are used for spraying of heat-resisting ceramic coatings on the gas-turbine hot section components surface by the plasma-chemical deposition techniques. The comparative study of the microstructure and phase composition for target specimens, which manufactured by vacuum-induction melting or vacuum-arc melting, are performed. The patterns of change in a microstructure and a phase composition in the experimental Zr–Y-based alloy, depending of manufacturing technology are shown. The aspects which have led to transformation of microstructure and phase composition of VTsM-1 Zr–Y-based  alloy at the change of the manufacturing technology of targets are detected.

The influence of climatic ageing on the properties of PCM-based epoxy resin systems

The article presents the results of studies of the properties of carbon fiber of the VKU-51 brand and fiberglass of the VPS-58 brand, made on the basis of the epoxy vinyl ester binder of the VSV-43 brand, after exposure in full-scale conditions of moderate and subtropical climate for 5 years with intermediate removals after 1 and 3 years. Physical and mechanical characteristics (strength and modulus of elasticity under tension, compression and bending) and glass transition temperature are determined. Studies have shown a high preservation of properties at 20 °C: 90–100% in VKU-51 and 73–100% in VPS-58, depending on the type of test.
