Microstructure Evolution of FeNiCoCrAlMo High Entropy Alloy during Powder Preparation, Laser Powder Bed Fusion, and Microplasma Spraying.

In the present study, powder of FeCoCrNiMoAl HEA was manufactured by gas atomization process, and then used for laser powder bed fusion (L-PBF) and microplasma spraying (MPS) technologies. The processes of phase composition and microstructure transformation during above mentioned processes and subsequent heat treatment were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and differential thermal analysis (DTA) methods. It was found that gas atomization leads to a formation of dendrites of body centered cubic (BCC) supersaturated solid solution with insignificant Mo-rich segregations on the peripheries of the dendrites.

[The emotional burnout effect on labor efficiency of stomatologists].

[Economic evaluation and rationale for human health risk management decisions].

The priority task of human health maintenance and improvement is risk management using the new economic concepts based on the assessment of potential and real human risks from exposure to poor environmental factors and on the estimation of cost-benefit and cost-effectiveness ratios. The application of economic tools to manage a human risk makes it possible to assess various measures both as a whole and their individual priority areas, to rank different scenarios in terms of their effectiveness, to estimate costs per unit of risk reduction and benefit increase (damage decrease).

[Future built-up area zoning by applying the methodology for assessing the population health risk].

Using the methodology for assessing the population health risk provides proposals on the functional zoning of the reorganized area of a plastics-works. An area has been allocated for possible house-building.

[The hygienic requirements for the organization of prehouse areas to create good living conditions for the population].

The paper considers the organization of prehouse areas, their improvement, and the adequate space of these prehouse territories to create good living conditions for the population. It has been found that the assessment of the existing town-planning situation in Moscow and the evaluation of the adopted functional zoning in the general town planning scheme for the city and administrative districts, and decision-making on the population's complaints require the estimation of the balance of a residential territory to develop normative requirements for this problem when considering the preconstruction proposals on location of variously purposeful projects in more detail, by analyzing the town-planning situation.
