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

An industrial vacuum arc remelting (VAR) furnace has been instrumented, enabling the electric arc to be observed for the first time during the remelting of a zirconium alloy. The system employed combined high speed video monitoring with synchronized high frequency recording of the arc voltage and was used to study the arc behavior and the mechanisms of liquid metal transfer from the electrode to the ingot. For current densities of the order of 10 to 20 A/cm2 and arc lengths less than 6 cm, the arc is of the diffuse multicathode spot type. The metal droplet transfer mechanisms depend mainly on the arc length. For small lengths, transfer is very often preceded by a drip-short, causing transitory extinction of the arc. For long arcs (> 3 cm), transfer is mainly by gradual erosion of the liquid induced by the cathode spots.
