The heat treatment focuses on precipitation hardening via a “solution treatment + aging” sequence to balance strength and toughness. Solution Treatment Eliminates lamination-induced stress and prepares for hardening. Heat to 1020–1060...

The core approach to improving the machinability of laminated steel plates is through a combination of material pre-treatment, process optimization, and tool adaptation to reduce processing difficulty, minimize defects, and ensure stable post-processing p...
