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: 1.1 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 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

Phase Doppler anemometry (PDA) and Extended phase Doppler anemometry (EPDA) are used for the characterization of powders produced with different melt atomization techniques. A laboratory scale production type melt spray facility was adapted for the application of PDA and measurements were performed in conventional gas atomization (CGA) of melts. In liquid gas atomization (LGA) of melts an extended phase Doppler system has been used allowing a distinction between melt particles and liquefied gas droplets.
In CGA, the results obtained with PDA show some discrepancies with off-line powder characterization techniques, however, variations of process conditions leading to changes in the powder size distributions could be successfully detected. Hence, a first attempt is presented how phase-Doppler anemometry can be incorporated in a process control loop.
In LGA, liquefied gas droplets and melt droplets could be successfully discriminated by using a sign of phase EPDA system. However, additional measurements are necessary to improve the reproducibility of the results.
