Perspectives of heat resistant structurally stable alloy VZh159 application for additive production of high-temperature parts of GTE

The microstructure features of VZh159 Ni-base superalloy synthesized by selective laser melting are reviewed in the article. It is shown that due to its high weldability this alloy forms better microstructure in comparison with similar alloys. Hot isostatic pressing and following heat treatment eliminate the anisotropy of the mechanical properties in synthesized specimens.

Keywords: Ni-base superalloy, selective laser melting, track structure, hot isostatic pressing

Testing EP718 and EP648 superalloys powders produced by FSUE «VIAM» for repair of gas turbine engine components using laser-powder braze

Application aspects of domestic EP718 and EP648 alloys powders to restore the geometry of laser gas turbine engine parts by braze are discussed in the article. The morphology of the particles and the fractional composition of applied powder materials are investigated. Influence of key parameters of braze on geometry of the built-up material are investigated. The features of structure formation of deposited material, change of microhardness on the fusing height and base material are considered. It is shown that the optimal practiced fusing modes provide with dense dendritic structure without cracks, pores, opalescences.

Keywords:  laser gas powder braze, metal-powder composition, protective environment, dendritic structure, cellular structure, micro-hardness, the braze material

Prospects of Ni3Al-based intermetallic alloy VKNA-4UR application in additive technologies

Typical defects of intermetallic cast alloy VKNA-4UR connected with adverse allocation of carbide phase are considered. It is found that selective laser sintering with warming creation platform allows forming dense material without any cracks, with uniform distribution of carbides in metal volume on grain boundaries. Evolution of the synthesized material structure after heat treatment and high isostatic pressure processing are investigated. It is demonstrated that uniform and discrete distribution of carbides remains at their coagulation, for the synthesized material after heat treatment the optimum «maze» of the g¢-phase morphology and higher quantity of secondary strengthening phase is detected, which lead to increase of fatigue life compared with the cast alloy. This work is executed within implementation of the complex scientific direction 7.3. «Creation of nickel-based intermetallic alloys and composite materials on their basis» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)

Keywords: selective laser sintering, additive technology, Ni3Al-based intermetallic alloy, γʹ -phase, microstructure, carbide phase

Application of Thermo-Calc software for determination of parameters of heat treatment 1913 alloy and temperatures of gas atomization for aluminium alloys

A number of parameters of aluminum alloys treatment depend on temperatures of phase transformations. For choosing these or those temperatures of heat treatment or preparing powders it is necessary to carry out the analysis of multicomponent phase diagrams. Thus it is useful to apply mathematical modeling for the process optimization. Results of thermodynamic modeling of multicomponent systems using the Thermo-Calc software are presented in the article. Good correlation of determination results of the phase transformations temperatures received experimentally and by the computational method is shown. The work is carried out under the realization of integrated research area 10.3. «Technologies of atomization for producing high quality metallic powders for additive manufacturing and powder for brazing» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)

The spheroidization of metallic powders (review)

The onrush of additive manufacturing in the domestic production has encouraged the development of domestic metal powders production technologies. The article describes the main principles of layer by layer additive synthesis technology of metal and ceramic-metal composite materials. The methods of the production of initial high-temperature composite material are presented. They are mechanical alloying, developed by FSUE «VIAM», and the production of exothermic mixture of transition metal and aluminum by self-propagating high-temperature synthesis followed by hot deformation of products used in IMET RAS. The technological necessity of the initial powder usage with definite morphology and particle distribution is described. The patents of different methods of the spheroidization are presented: preparing powder particles in the flow of thermal plasma, physical vapor deposition, laser spheroidization.

Keywords: methods of spheroidizing, metal-ceramic powder composition, additive manufacturing, spheroidization of powders

Investigation of phase transitions and structure of the polymer powder compositions based on polydodecanolactam obtained by crystallization from solutions in polar aprotic solvents

He article presents data on phase transitions and structure of the polymer powder compositions obtained by crystallization from polydodecanolactam (polyamide 12 - PA-12) solution in polar aprotic solvents. It is shown that fractional composition of the powder and morphology of the particles drastically depend on the temperature of deposition mode, the type and amount of crystal-forming fillers. The prepared experimental compositions have an average diameter 70-100 micron, a coefficient of circularity in the range of 1.1-1.2. Applying the method of crystallization solutions in polar aprotic solvents allows to obtain polymer powders with phase transitions (melting and crystallization) comparable with the PA 2200 (EOS GmbH) base material for SLS. The research results will be used in the development of the range of polymer powder formulations for the SLS additive technology.

Keywords: polydodecanolactam, polyamide PA-12, polymer powder compositions, materials for additive technologies, selective laser sintering

Low-cycle fatigue resistance of PM Ni-base superalloys (review)

To assess the item workability in the operation, in addition to the static parameters and long-term strength gas turbine engine (GTE) developers need to have data on the characteristics of low-cycle fatigue resistance, taking into account the real factors. Basic material requirements of GTE disks in terms of a given resource in the operation are presented. Particularities of control of the mechanical properties of granular heat-resistant nickel alloys are considered. The existing research scenario of the low-cycle characteristics of granular materials is described. Research on the distribution of nonmetallic inclusions (depending on size) in different p/m alloys used for the manufacture of turbine disks is presented. The work is executed within implementation of the complex scientific direction 10.2. «Isothermal deformation on air of new generation of heterophase difficult-to-form hot strength alloys» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
