A new friction-based riveting technique, Rotating Hammer Riveting (RHR), is demonstrated to fully form AZ31 Mg rivet heads in a mere 0.23 s. Heat and pressure generated through severe plastic deformation during the process was sufficient to form the Mg rivet head without the need for a pre-heating operation. Due to preliminary twinning and followed by dynamic recrystallization, AZ31 Mg grains in the rivet head were refined during RHR, which enhance the formability of Mg rivets by triggering grain boundary sliding and reducing plastic anisotropy of Mg. In addition, RHR joints showed a metallurgical bond between the rivet head and top AZ31 Mg sheet, which eliminates a significant pathway for corrosion.

一种新的基于摩擦的铆接技术，旋转锤式铆接 (RHR)，被证明可以在 0.23 秒内完全形成 AZ31 Mg 铆钉头。在此过程中通过严重的塑性变形产生的热量和压力足以形成镁铆钉头，而无需进行预热操作。由于预孪晶和随后的动态再结晶，铆钉头中的 AZ31 Mg 晶粒在 RHR 过程中被细化，通过触发晶界滑动和降低 Mg 的塑性各向异性来提高 Mg 铆钉的成形性。此外，RHR 接头在铆钉头和顶部 AZ31 镁片之间显示出冶金结合，从而消除了重要的腐蚀途径。
