Abstract:
The aim of this study was to determine the influence of selective laser melting (SLM) process parameters on the formation of cracks in nickel-based single crystal alloy. Several sets of laser scanning parameters, with varied laser power, scanning speed and hatch distance, thus resulting in different volumetric and linear energy densities, were investigated. [..]

Abstract:
Elastic properties of wound rolls are used as an input for simulations of stress-strain state in the roll after winding in order to optimize quality of foils. The effective elastic modulus in direction perpendicular to the layers of foil is challenging to measure because it is dependent on interlayer pressure and is generally much smaller than the bulk elastic modulus of the material.

Abstract:
The effect of high-energy ball milling a mixture of Fe and h-BN with weight ratio of Fe:BN = 15, 4, 1, 0.36 on the phase composition and magnetic properties of the synthesized material has been investigated. High-energy ball milling demonstrated a significant change in the phase content, structure, and magnetic characteristics upon MA and followed annealing at 600 0C, in particular upon annealing, and the coercivity of the MA powder reached HC = 43 kA/m (540 Oe)..

Abstract:
The depletion of ores from the first sources on one hand has led to using damped materials that contain valuable metals to be recycled while environmental threats are being targeted and on the other hand high price of reductant coupled with their depletion have caused a stir in the metallurgical industry. Many slags are currently recycled for the recovery of valuable metals while new reductants are being tested for eventually replace the generic reductants. [..]

Abstract:
In the course of the work, a resource-saving version of the work of all basic elements was developed. The developed technological scheme will allow wastewater to be treated to modern maximum permissible concentrations (MPC) standards due to the highly efficient removal of heavy and non-ferrous metals and organic impurities, which can significantly reduce the cost of water supply to the enterprise..
