Correction to: International Journal of Metalcasting https://doi.org/10.1007/s40962-019-00322-3
In the original article, the authors neglected to explicitly state prior to presentation of results for the as-cast water-quenched (ACWQ) plus tempered coupons from the November, 2012 (Y2012) fade campaign that all reported velocities were measured prior to tempering, as the tempering was necessary only to facilitate the sectioning of those coupons by conventional band saw for their metallographic analysis. The tempering of such ACWQ coupons at 482 °C for 48 h raises their velocities by ~ 100 m/s.
