Director/Chair, Content Development & Dissemination and Professor, University of Alabama at Huntsville. “IMMI explores innovations that build on integrated computational materials engineering (ICME), from the discovery of materials through their manufacture,” VDLG6FKQHLGHU³7KHMRXUQDOUHÀHFWVWKH FRQYHUJHQFHRIVHYHUDOUHVHDUFK¿HOGV toward the goal of accelerating discovery through multi- and interdisciplinary research areas. A complement to accelerated discovery is the consideration of sustainability of metal-producing industries, with an emphasis on materials recovery, UHXVHDQGUHF\FOLQJ)RUWKHVHH൵RUWVJSM captures the emerging research.” A journal’s Impact Factor is the average number of citations counted in a given Impact Factor year for articles published in the two preceding years. It is based on the number of citations of a journal’s content divided by the number of citable articles published by that journal. Impact Factor is just one of many factors to consider when evaluating journal performance. The Impact Factor is a measure of the impact of a journal, and not of the quality of the published research.

“This year’s release marks the first Impact Factors for Integrating Materials and Manufacturing Innovation (IMMI) and Journal of Sustainable Metallurgy (JSM), both of which achieved strong debut numbers.”

The 2019 Journal Citation Reports (Clarivate Analytics, 2020) were released in late June and included Impact Factors for all six TMS journals. This year’s UHOHDVHPDUNVWKH¿UVW,PSDFW)DFWRUVIRU Integrating Materials and Manufacturing Innovation (IMMI) and Journal of Sustainable Metallurgy (JSM), both of which achieved strong debut numbers. The following list shows the 2019 Impact Factors for each TMS journal, with a comparison to 2018 in parentheses for journals that received an Impact Factor for that year: • Integrating Materials and Manufacturing Innovation: 3.447 (n/a) • JOM: 2.029 (2.305) • Journal of Electronic Materials: 1.774 (1.676) • Journal of Sustainable Metallurgy: 2.109 (n/a) • Metallurgical and Materials Transactions A: 2.05 (1.985) • Metallurgical and Materials Transactions B: 2.035 (1.952) The success of TMS’s two newest MRXUQDOVUHÀHFWVWKHFKDQJLQJODQGVFDSH of materials science and engineering, according to Judy Schneider, TMS

Baker and Zappas

While Impact Factor can vary from year to year for a variety of reasons, TMS journals have generally tracked in a positive direction (see Figure 1 on previous page), and have also achieved strong placement in Clarivate’s ranking by subject categories (see Table I).
