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: 1.4 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: 1.3 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

Краткое описание

A physically based constitutive model capturing the reduced strain-rate sensitivity of dilute solid solutions is developed. The decrease of the strain-rate sensitivity parameter is associated with the variation of the strength of dislocation junctions with the size of solute clusters forming on forest dislocations. It is shown that the strength of junctions formed by unclustered mobile dislocations and clustered forests increases with the size of the cluster and, therefore, with the aging time of forests. The formulation is calibrated based on results obtained from mesoscopic models of dislocation interactions in the presence of solute clusters at forest dislocations. The strength of junctions is evaluated for most geometries and an averaging procedure is used to predict the strain-rate sensitivity. Several features observed experimentally are reproduced by the model. Its limitations are discussed in closing. The data may also be used as input for discrete dislocation dynamics simulations.
