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.
Claims39
An article of manufacture, comprising:
- a metal substrate;
- and
- a stack of alternating metal and intermetallic layers metallurgically bonded to one another and to a surface of the metal substrate, wherein each metal layer comprises a first metal and each intermetallic layer comprises an alloy of the first metal and a second metal, wherein thickness values of the layers in the stack are spatially graded.
An article of manufacture, comprising:
- a substrate comprising a first metal;
- a stack of alternating metal and intermetallic layers metallurgically bonded to one another and to a surface of the substrate, wherein each metal layer comprises the first metal and each intermetallic layer comprises a compound of the first metal and a second metal;
- and
- a plurality of metal wires penetrating through the stack and each having a portion embedded in the substrate, each metal wire metallurgically bonded to the stack and substrate.
1 more element
An article of manufacture, comprising:
- a stack of alternating metal and intermetallic layers metallurgically bonded to one another, wherein each metal layer comprises the first metal and each intermetallic layer comprises a compound of the first metal and a second metal;
- and
- at least one sensor embedded in the stack operable to measure a parameter indicative of a condition of the stack.
An article of manufacture, comprising:
- a stack of alternating metal and intermetallic layers metallurgically bonded to one another, wherein each metal layer comprises a first metal and each intermetallic layer comprises an alloy of the first metal and a second metal;
- and
- a closed metal box enclosing the stack, wherein each inner wall of the closed metal box is metallurgically bonded to the stack.
