RETRACTED: Influence of cobalt phase on thermal shock resistance of Al2O3–TiC composites evaluated by indentation technique

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). rticle has been retracted at the request of the Editor-in-Chief. rresponding author of this article informed Materials Research Bulletin on 1 August 2014 of the existence of a very similar paper, written in Chinese by the same group of co-authors and published in the Journal of Inorganic Materials (2007, 22(1), 106-112) by The Science Press. In the view of Materials Research Bulletin, authors have a responsibility not to engage in redundant publication, which occurs when two or more papers share the same hypothesis, data, discussion points, or conclusions - all of which overlapped in these two papers. In particular, figures 2, 3, 4, 5, and 7 as well as table 4 in the Materials Research Bulletin paper all appear in the earlier Chinese work as figures 5, 6, 1, 8, and 4 and table 4. Such redundancy is not only a violation of the copyright held by Journal of Inorganic Materials, but is an affront to scientific publishing ethics. The editorial board and publishers of Materials Research Bulletin are grateful to the authors for bringing this situation to our attention.
