The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRACT

X-ray structure investigations of nanosized aluminum and copper powders prepared with a transient plasma process by wire electrical explosion (WEE) have been carried out To compare structural characteristics, powders produced by conventional routes have also been investigated. Calculations of lattice parameter values in different plane (hkl) directions were done using experimental data. Visible deviations of lattice parameter vataes for nanosized powders, in comparison with JCPDS references and powders prepared through conventional pathways, have been found out. To determine the influence of the dimensional fector on microdeformations, all specimens were divided into sub-micronic and nanometric fractions by the sedimentation in cold absolute alcohol. According to X-ray structure analysis, the increase of lattice parameter is more considerable in the submicronic fraction of electroexplosive powder than that of nanometric fraction. The conclusion was made that severe conditions of etectroexplosive powders fabrication, as well as different cooling rates of particles, can play an essential role in the deformation of their crystal lattice. In addition, we may conclude that the deformation of the crystal lattice corresponds to an energy excess stored in these nano-sized powders prepared with the wire electrical explosion technology.
