Abstract
Fabrication techniques for and examples of metallic composite materials with high toughness, high strength, and lightweight for various structural, armor, and structural-armor applications. For example, various advanced materials based on metallic-intermetallic laminate (MIL) composite materials are described, including materials with passive damping features and built-in sensors.
Claims22
A method for manufacturing an article, comprising:
- providing a metal box having an opening and a metal lid plate for closing the opening;
- placing a stack of alternating first metal and second metal layers inside the metal box, wherein a first metal in the first metal layers and a second metal in the second metal layers are operable to react under heat and pressure to form an intermetallic material;
- closing the opening with the metal lid plate to compress the stack inside the box to contact each inner metal wall of the box;
- and
- applying pressure and heat to the closed metal box to compress the stack and to cause reaction between two adjacent layers in the stack and reaction between the stack and each inner metal wall of the box to form metalurgical bonding between adjacent layers in the stack and between the stack and the metal box.
