During nitriding, a thin compound layer and a relatively thick diffusion zone are produced on the surface of the component.
Increasing nitriding temperature to 500°C resulted in similar diffusion zone depth but formation of about 2 µm thick g’ (Fe4N) compound layer.
During nitriding nitrogen diffuses in the surface layer of the treated part where due to low solubility of nitrogen in iron it forms nitride precipitates with iron and alloying elements.

The aim of this paper is to show that recent progress in modelling of the role of grain boundaries in metallic materials offers new possibilities for optimizing their properties.
Nevertheless, the currently available models do provide a useful insight into the properties of so called special grain boundaries, with specific rotations angles, which comprise a significant fraction of the grain boundaries in ultra-fine- and nano-grained aluminium alloys (see for example [18, 19]).
Grain boundaries revealed in 2014 aluminium alloys: the coloured lines indicate the grain boundaries of mis-orientation angle from different ranges.
A finite element model of nano-polycrystalline aluminium alloy is shown in Figure 8.

The mechanism of this type of corrosion is not explained so far because combustion gases are very complex, containing in addition to carbon oxide, water vapor, nitrogen oxides, sulphur, alkali metal compounds as well as acetic and formic acids.
Thus, the aim of the present paper is to explain the role of acetic acid on the corrosion processes of X33CrNiMn23-8, X50CrMnNiNbN21-9 and X53CrMnNiN20-8 valve steels.

This paper aims to provide an overview of the state of the art in such joining processes, including cold welding, friction stir welding, joining by forming, self-pierce riveting and mechanical clinching.
Lap joining is typically applied to join aluminium-aluminium, aluminium-copper, copper-copper including alloys for electricity supply.
Such joints also provide a good seal. 2-stage shear spinning is used to manufacture compound structures as shown in Fig. 8 [16].
Rotary swaging is also available to manufacturing of the same compound structures.

Nano-technology is a high-tech industry, which aims to explore and work at atoms and molecules [2].
Therefore, a number of investigations are concentrated on examining the influence of tungsten carbide on properties of refractory alloys, which has high thermal stability, increased modulus of elasticity and lower thermal expansion coefficient as against other metal carbides [28, 29].
