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: 0.7 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: 0.7 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: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RÉSUMÉ

Low vulnerability gun propellants are energetic materials designed to resist unintended ignition stimuli. The present work aims to determine kinetic parameters for two insensitive powders. The first propellant is made of 1,3,5-trinitro-1,3,5-triazinane, usually called hexogen (RDX), and hydroxyl-terminated polybutadiene as a binder. The second one is a nitrocellulose (NC) based propellant, which also contains diphenylamine. These propellants are commercial products and were provided by ArianeGroup. Both propellants have a cylindrical shape with several perforations. Only a few milligrams of each sample are used in this study. Combustion properties of these samples were already studied and published concerning the RDX- and NC-based propellants. This experimental study focuses on two thermal analysis methods, which are the thermogravimetric analysis (TGA) and the differential scanning calorimetry (DSC). This study is complementary to the previous works on combustion behavior. Data obtained with such thermal analysis techniques provide important results concerning thermal behavior of propellants. These results are useful to study ignition and combustion, but also storage (aging). For each propellant, DSC and TGA analyses are performed using several heating rates to obtain their activation energies. Comparison of their reactivities is done by working under two different gaseous atmospheres (argon and nitrogen). Activation energies obtained using the two techniques and under the two atmospheres are given, discussed, and compared to literature available data.
