Thermal fatique of superalloys

The material deformation is developed under the restriction conditions at the thermal effect due to the active mechanism of extension-compression. Under the cyclic repetition it leads to the formation of a substructure, favourable for the crack nucleation, particularly at the cooling stage and increasing the tensile stresses. The characteristic features of the single crystal deformation, including the long - term retention of the initial axis crystallographic orientation were marked at the multiple cyclic heating and cooling.

Rhenium extraction out of wastes after the treatment and service of Ni-base superalloys

The study results in the field of rhenium regeneration out of Ni-base superalloy wastes are given in the paper. Two schemes, including the acid treatment of wastes were suggested in this case. The first variant envisaged the transfer of the alloy base into the solution and Re concentration in the leached residue. In order to extract Re out of the residue, the high-temperature oxidation method was tested for Re 2O 7 skimming. The second variant was carried out under the oxidation conditions, which ensured the transfer of the alloy base and rhenium into the solution. The selective rhenium extraction out of solution was performed by the liquid extraction method with the use of secondary octyl alcohol. Due to the last variant the specimens of ammonia perrhenate refining from the basic quantity of impurities were obtained.

Variation of mechanical properties of GS3LS-VI superalloy depending on the hafnium content

The effect of hafnium additions in the alloying range from 0,1 to 0,9% (by weight) upon the structure and mechanical properties of GS3LS-VI alloy was studied. The results of mechanical tests and metallographical investigations are presented for the experimental compositions with the different hafnium content in the studied alloying range compared to GS3LS-VI alloy without hafnium additions. The optimum alloying of GS3LS-VI alloy by hafnium promotes the formation of the favourable microstructure and the mechanical characteristic increase.

Hardness, as the corrosion indicator of aluminium Alloys under the marine conditions

One of the existing problems of studying the corrosion processes is the absence of accurate and trustworthy methods for determining the integral corrosion state. The existing methods either are not enough accurate or reflect only one side of corrosion process, for example, the weight losses give the information of the general corrosion only, but they are not susceptible to the intercrystalline corrosion. Hence, the significant field of science relative to corrosion is the search of new methods for determining the characteristics of corrosion state. Now the principally new method was proposed for the determination of corrosion state on Al-base alloy surfaces. This method is based on the multiple measurements of the surface hardness.

Keywords: corrosion, aluminium alloys, material hardness

Radiotransparent glassceramic material with the improved distribution of physico-technical properties

The data necessary for the production of a glassceramic material of recrystallized lithiumalumosilicate glass (OTM-357-O glassceramic) are presented in the paper. The produced glassceramic is the analogue of the well-known OTM-357 material, but it possesses better distribution of physical and technical properties through the whole volume of its products. The property comparison of both materials showed that the produced material didnʹt yield to the analogue in a number of properties and even exceeded them, for example, the dielectric characteristics.

С omplex thermodiffusion high-temperature coatings for Ni-base carbon-free superalloys

It was stated, that the protection against the high-temperature gaseous corrosion for single - crystal turbine blades, made of carbon - free superalloys (CFS) with the high content of refractory elements (Re, Ta) for advanced GTE turbine blades was possible with the use of complex high-temperature and thermoprotective coatings being produced with the various combination of chemical and physical deposition methods. The original deposition process was suggested for producing the complex high-temperature thermodiffusion coatings with the barrier layer on the base of refractory matrix carbides for the CFS protection against the high - temperature gaseous corrosion.

The review of todayʹs developments and properties of sealing materials on the base of polysulfide and silicone polymers is presented in the paper along with their application in the field of aircraft building. In this case the silicone sealants, capable to be used within the wide temperature range from -100 to +300 ° C are of particular interest. In connection with the loss of commercial production of sealants with the maximum thermal resistance above 300 ° C the perspectives of their industry rehabilitation, including the necessity of heat and freeze-resistant silicone copolymer synthesis are considered for the development of pointed materials. The analysis of information data, concerning the methods for improving the thermal resistance of silicone elastomeric materials was carried out and the basic synthesis areas of liquid silicone copolymers with the given chemical structure were chosen for the development of sealants with the maximum thermal resistance up to 400 ° C.

Keywords: sealing materials, polysulfides, silicone polymers, structure joining, heat and freeze resistance, cockpit sealing, glazing “cold” vulcanization, catalysts, thermal resistance, freeze resistance, elasticity, sublayer-free sealant, thermal resistance increase, distructive stability, reactive groups

Test methods and the calculative determination of fatigue limit for the horizontal fatigue curve area

Fifteen specimens are usually subjected to testing in order to determine fatigue characteristics of a material. If the fatigue curve has the horizontal area, i. e. the physical fatigue limit so in this case itʹs possible to define only the average value of fatigue limit. The fatigue testing method and the data processing are suggested in the paper along with the use of the step-by-step loading changing method, which allows to calculate the average value of fatigue limit to a high precision. This method also gives a possibility to define the minimum value with any given non-destruction probability. In doing so, the total quantity of test specimens is equal to 32 pcs.
