Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Hot deformation bonding (HDB) offers a promising approach to producing superalloy joints with base‐metal‐level strength, provided that interfacial microstructure is reconstructed through dynamic recrystallization (DRX). Current studies on DRX at bonding interfaces neglect actual phase‐contact configurations, obscuring interfacial DRX ...
