Retraction notice to “Enhanced mechanical properties of a large-size metallic alloy through a gradient microstructure” [j.msea.2019.138193] (Materials Science & Engineering A (2019) 764, (S0921509319309797), (10.1016/j.msea.2019.138193))

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Authors. The authors contacted the journal to report the inappropriate comparison between their own compression tests results and the compression and tension tests results included in Fig. 7. Unfortunately, the necessary changes cannot be addressed in a corrigendum and would warrant a new manuscript. It is important to note that this is not considered to be the result of scientific misconduct, but rather honest errors by the authors.
