STRUCTURAL FEATURES DESTRUCTION OF MONOCRYSTALLINE MATERIALS

The features of the production of single-crystal blades from nickel heat-resistant alloys are considered. Metallographic and fractographic studies of the destroyed blades were performed to identify the causes of destruction. The features of fatigue and static destruction of single-crystal turbine blades have been studied by optical and scanning electron microscopy using X-ray spectral microanalysis. Recommendations are given to prevent the formation of recrystallized polyhedral grains.

EXPLOITATION PROPERTIES OF ANTIFRICTION SELFLUBRICATING ORGANOPLASTIC BASED ON FABRIC MADE OF POLYTETRAFLUOROETHYLENE AND ARCELON FIBERS

The article studied the exploitation properties of antifriction organoplastics based on a new reinforcing fabric consisting of two types of fibers: polytetrafluoroethylene and polyoxadiazole fiber Arcelon. The nature of destruction during delamination of organoplastic from a metal substrate and the influence of various factors (temperature, humidity, salt fog, tropical chamber conditions, etc.) on adhesive strength were studied. It has been shown that, under the influence of operational factors, organoplastic has high adhesive strength values – above the allowable minimum level.

INFLUENCE OF DIRECTED CRYSTALLIZATION PARAMETERS ON STRUCTURE AND PROPERTIES OF ALNICO 5-7 ALLOY PERMANENT MAGNETS

In this paper has been investigated influence of direct crystallizations parameters on permanent magnets alloy UNDKBA (Alnico 5-7) for non-defective percent. For this paper were produced permanent magnets by using different types of seeds and technological parameter. It established that the main parameters for manufacturing castings permanent magnets are temperature, broaching speed, composition and type of the seed. Revealed that slow broaching speed, monocrystalline seed with the crystallographic orientation allows to obtain permanent magnets with non-defective percent higher than 80.

MODELING THE DESTRUCTION OF A METAL-CERAMIC COMPOSITE MATERIAL WITH A MULTILAYER STRUCTURE BY THE FINITE ELEMENT METHOD

The purpose of this work is to determine the effect of the transitional diffusion zone at the interfacial boundary of the layers of the ceramic composite material of the Mo–Si–B system on the nature of destruction and physical and mechanical properties. Qualitative models have been created that make it possible to predict the most critical fracture zones of a composite material, and the effect of microstructure on the fracture mechanisms has been studied. Field tests of a ceramic-metal composite material with a multilayer structure were carried out, as a result of which a high convergence with the calculated models was established.

ENERGY CRITERIA FOR FATIGUE FRACTURE OF A HEAT-RESISTANT NICKEL ALLOY

Tests for low-cycle fatigue of a heat-resistant nickel alloy were carried out at operating temperature, deformation of tensile cycle and a frequency of 1 Hz. On the example of the obtained data of elastic-plastic deformation, the material constants of the Manson–Coffin and Ramberg–Osgood equations are determined. The main relationships that use the energy of destruction, necessary for predicting fatigue life, are considered. It is shown that the application of the energy criterion in terms of the accumulated strain energy density parameter more accurately describes the fatigue behavior in the low-cycle fatigue regime. The data obtained will make it possible in the second part of the article to use the energy criterion to predict the durability of the alloy under study under conditions of stress concentration.
