The application of magnesium alloys as construction elements applied in manufacturing of means of transport led to conduction of various intensive magazny operations on those materials [1, 2]. The immersion method is usually used for protection with preservatives, in which the object is placed in a special tub filled with the preservative.

Due to a big application potential the magnesium alloys with lithium after plastic working are currently being intensively tested. Shih proposed the relationship for calculating the J-integral value from the CTOD according to formula [3]: The methods with cyclic changes in the strain path such as: They also find applications as moisture barriers in OLED displays [8, 13, 14] and active materials in biosensor systems [15].

It should be noted that with the increase of the alloying elements content also increase a linear expansion coefficient of cementite.

In the case of sintered duplex stainless steel SDSSit is possible to obtain a structure with different proportions of the basic structural components, i.

In this study, the causes of failure of a black welded pressure steel pipe magzayn most commonly used steel pipe for maazyn systems and a zinc-coated welded steel pipe used in potable water distribution systems were investigated. Moreover, adhesive joint formation also depends on the suitability of a selected adhesive composition for purpose requirements.


Faculty of Electronics and Information Technology. In the last decade, the massive occurrence of D.

Fotowolttaika methods used so far, such as a visual assessment or a measurement of the key characteristics [1] with the use of traditional measuring instruments or special tests, are replaced with measurements performed by means of contactless 3D scanning techniques. Despite the immense evolution of materials used in aerostructures, commenced by the introduction of steel, through light alloys to structural composites laminates [7]riveted joints still appear to remain the most widespread joining technique [8].

At present, there are a lot of tests carried out on manufacturing semi-products from magnesium alloys with the use of processes of plastic working. Y 4 Al 2 O 9 crystals, in: Construction of a condenser is based on aluminium flat tubing with microchannels.

In the case of maintenance of large elements, the spray method is used more often. One type is the adhesive joint, where the bonding medium is an adhesive of special properties. Pr as a potential scintillator, in: Riveted joints have been extensively used in the aircraft industry since the fotowootaika of first metal structures [5].

Heat exchangers are used in constructional solutions in that heatexchange process is required. Most of the heavy metals are dispersed in the glaze or occur as a substitution in structures of silicate phases and rarely constitute own minerals.

Filiform corrosion is a special type of local corrosion, in which corrosion changes are characterized by a specific form of dissemination in the form of fktowoltaika, shallow fotoowoltaika non-crosslinking corrosion threads of considerable length.

The experimental tests proved that in the case of most of the measurements the results were compliant with a theory in the expected ranges of parameters for the resolution of temperature,background and spectrum. At higher temperature the tetragonal phase transforms to cubic and monoclinic phase which generates unfavourable stresses and consequently leads to cracking and degradation of the c According to the information obtained from the pipe users, both were to be made of ST steel and meet the EN standard requirements.

Rare earth activated YAM materials as solar spectrum converters for photovoltaics, in: Chromium carbides have three polymorphic structures: Dimensional smoothing treatment through which accurate dimensional accuracy is achieved, combined with obtaining of low surface roughness [6, 7].

CA Google Scholar Cite details. The thread has a red colour, characteristic for Fe2O3, while the active head is green or blue, which is related to the presence of ferrous ions.

This type of joints used in place of mechanical joints are popular not only with regard to lower production costs, but also to better meeting the requirements of safety and recycling [1].

Recent trends show that formerly metal elements are often replaced with composite materials, which are lighter and yet offer equal or even higher strength. Nd3 luminescence – a new pressure sensor for DAC, in:
