The International Journal of Metalcasting, upon review with the corresponding author F.H. Samuel, is retracting the article “Parameters Controlling the Impact Toughness of A356.2 Cast Alloy”. Upon review with the author it was felt that, by an oversight on their part, significant content portion of the aforementioned paper was contained in a paper previously published by the authors in Material Design, doi:10.1016/j.matdes.2013.10.029. The authors requested that the IJMC paper be retracted. We appreciate the authors verifying this potential issue and conferring upon this decision.
