“…The authors of the study in [8] investigated the iron scale reduction by carbon within the range of 1023-1323 K, with the detection of Fe 3 C and carbon along with the iron phase in the resultant products. Residual iron oxides appeared only after heat treatment at a temperature of 1023 K. In contrast, as indicated in [10], the additional presence of tungsten seems to have had an effect on the nature of carbide formations, which affected the microstructure's features. Some particles, probably carbide ones, with high levels of carbon, tungsten, and other elements, were found.…”

The features of structural and phase transformations during the processing of alloyed metallurgical wastes using reduction smelting are determined herein. This is necessary in order to determine the technological parameters of the melting process that ensure the reduction in the losses of alloying components. The use of X-ray phase analysis in combination with the methods of raster electron microscopy and X-ray microanalysis ensured the identification of the microstructure features and the chemical composition of individual phases and inclusions in the metal. Our study identified new technological aspects of high-alloyed technogenic waste processing using reduction smelting. The obtained parameters of the resource-saving alloying compound provide the possibility to replace parts of the standard ferroalloys in steelmaking processes.

Designing virtual environments for attitudes and behavioral change in plastic consumption: a comparison between concrete and numerical information

et al. 2020

Starting from the pro-environmental potential of virtual reality (VR), the aim was to understand how different statistical information formats can enhance VR persuasive potential for plastic consumption, recycling and waste. Naturalistic, immersive virtual reality environments (VREs) were designed ad hoc to display three kinds of statistical evidence formats, featured as three different formats (i.e., numerical, concrete and mixed). Participants were exposed only to one of the three formats in VR, and their affect, emotions, sense of presence, general attitudes toward the environment, specific attitudes and behavioral intentions toward plastic, use, waste, recycle, as well as their social desirability proneness were measured. Numerical format was the least effective across all dimensions. Concrete and mixed formats were similar. Social desirability only partially affected participants' attitudes and behavioral intentions. Numerical format did not increase the persuasive efficacy of statistical evidence displayed in VR, with respect to visual alone. Implications and future directions for designing effective VRE promoting pro-environmental behaviors were discussed.
