title: RETRACTED: Effect of electropulsing treatment and ultrasonic striking treatment on the mechanical properties and microstructure of biomedical ti-6Al-4V alloy.
abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).
  
  This article has been retracted at the request of the Editor-in-Chief.
  
  The authors have reused figures and text that have already appeared in their previous articles. Figure 6a duplicates figure 6a (horizontally flipped) in Reference [1], while figure 6c duplicates figure 6c in Reference [1] and figure 3c in Reference [2] (albeit different scale is reported for each of these three figures). Figure 7 duplicates panels from figure 9 in Reference [3].
  
  The article also duplicates parts of the text that appeared in Reference [1].
  
  One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents an abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
  
  Journal records indicate that confirmation of the submission and publication of the article was sent to the first author’s email address but not to the corresponding author's email address.
