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.

[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).
