Abstract

The bulk metallic glass (BMG) bonding with a thin elemental crystalline layer has been examined in terms of electro discharge technique. The estimated temperature rise during electro discharge was up to about 3500 °C, and thus the interface involved a liquid phase. When the optimized database was applied to fabricate the two-layered BMG (BMG/Zr/BMG), the interface between crystalline layer and BMG showed a well-bonded interface and the fracture toughness of the two-layered BMG exhibited higher value compared with monolithic BMG. The detailed calculation for input energy and the main mechanism for the higher toughness are discussed.
