Microstructure and properties investigations of Fe–Cr–Ni stainless steel obtained by selective laser melting

Microstructure investigations of Fe–Cr–Ni stainless steel’s sintered samples obtained by selective laser melting were held. Mechanical properties and corrosion resistance of the samples at the initial state and after treatment were estimate. It is shown that material’s structure consists of fine grain sells oriented along the crystallization direction. After hot isostatic pressing and heat treatment microstructure becomes more homogeneous and takes the form of identical one of the casting material. Anisotropy of the mechanical properties intrinsic to the sintered state is not observed.

Investigation structure and properties of seam weld from heat-resisting steel VZh159-ID

The article considers the technology of electric fusion welding of heat – resisting alloy VZh159-ID and the determination of optimal modes of heat – treated samples in the order to achieve a high – quality weldments that are maintaining heat – resisting properties and the age – hardening ability.

A welding seam and a heat – affected zone expand as the result of the heating process. Actions made at the side of the less heated part of the element and are directed to the high – heat area cause the compressive deformation that is turning into the inelastic one. The deformation arising with later cooling prevents the decreasing of the welding seam and leads to the emergence of the tension stress. The reduction of the level of residual stresses is performed by the heat treatment of the welding assembly. The temperature of the heat treatment leads to tension stress relieving and hardens the welding seam. It is necessary to provide the depression strengthening of the welding seam and the parent metal both taking into account specific properties and thermal actions.

In the case of age hardened details and weak welding seam the reduction of the level of residual stresses is better to perform using the local heat treatment in the heat – affected zone.

The local heat treatment like as isothermal one should provide the depression strengthening of the welding seam without thermal overload of the material and take a little time to prevent the age – hardening of the base metal.

The determination of the temperature ranges of the welding seam changing under the heat process and optimal modes of temperature level is performed using the method of X-ray photoelectron spectroscopy. The sample is heated by step – by – step method of election &

Technological features of the manufacture of thick-walled parts of the PCM (review)

Thick-walled parts made of polymer composite materials (PCM) are used in the aviation, railway, construction and other industries. Their manufacture has a special feature – when forming a structure, zones with elevated temperature may appear due to a sharp jump in the exothermic effect, which can lead to residual stresses leading to cracks and delamination, destruction of the material, and even ignition of the part. This review discusses various ways to reduce this effect when forming a structure.

Fiber-matrix adhesion strength measurement using nanoindentation (review)

The review briefly reviewed the applied methods for determining the fiber-matrix adhesive strength. The main emphasis is on measuring the adhesive strength by the single fiber push-out method using instrumental micro- and nanoindentation. The issues of informativeness of this approach, modeling of the process of pushing the fiber by the indenter, the stress state in this process are considered. Attention is paid to the methods of testing, in particular, the features of sample preparation, the geometry of the indenters used, loading conditions.

Effect of sintering additives on the properties of silicon carbide-based ceramics (review)

Silicon carbide has a number of unique physical and chemical properties. Studies in the field of silicon carbide-based materials densification in the synthesis process have shown that a promising method of consolidation is liquid-phase sintering with the additives of different composition, contributing to reduction of the synthesis temperature to 1850°C, intensification of diffusion processes, filling of intergranular pores and restructuring of silicon carbide grains. In this paper the modern approaches to modification of silicon carbide-based ceramics with the additives of different composition are considered.

Research of dependence of adhesion of ice to polyurethane coatings from their physicomechanical properties

Development of the materials preventing frosting of various designs is one of relevant tasks of the modern polymeric industry. In this work, we studied the adhesion characteristics of ice to coatings based on polyurethanes of various grades: polypropylene glycol, polybutylene adipate, polycaprolactone diol, fluorine-containing oligodiol of the MAOK brand, including those modified with carbon Taunit-MD nanotubes. Researches of dependence of the dynamic module of elasticity of polymeric matrixes on temperature are conducted. It is shown that the elastic modulus of the investigated coatings lies in the range from 116 to 297 MPa. The amount of adhesion of ice to the investigated coatings ranges from 40 to 210 kPa. Introduction to structure of initial polyurethane compositions of carbon nanotubes leads to decrease in glass transition temperature the coatings. It is established that the size of adhesion of ice to the studied coatings is defined by the coatings thickness, density of a grid of cross chemical stitchings and also structure of a physical grid of gearing.

Influence of the type of loading on high-cycle fatigue of heat-resistant alloys

As is known, in domestic and world practice it has historically developed that in research and certification of alloys, high-cycle fatigue tests are carried out according to the «pure bending with rotation» loading conditions. Nowadays most scientist around the world give preference to high-cycle fatigue tests according to the «tension–compression» loading conditions. This article is about to assess the influence of the type of loading on high-cycle fatigue of nickel heat-resistant alloys GS6U, EI698 and heat-resistant titanium alloy VT8M-1.
