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: 1.3 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.7 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: 0.7 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: 0.00023 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: 0.11 SJR: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

RESUMO

The process of crack propagation from the pore in modeled microstructures of the submicron and nanostructured WC/Co hard alloys with different volume fractions of the cobalt phase was studied. Strengths of these alloys were found. The correspondence of the energy release rate to the component fracture toughness was the criterion of crack propagation through cobalt interlayers and carbide grains. To calculate energy release rate, the stress state was simulated by the finite-element method. It was shown that stresses required for crack propagation reach the maximum value, when the crack comes up to the middle of the cobalt interlayer after tungsten carbide destruction.
