Introduction MAX-phase Properties My project Structure
3
MAX-Phase Ternary Carbides / Nitrides Family formula: M n A X n-1 M= Early Transition Metal A= Elements from Group 12-16 X= Carbon or Nitrogen
5
MAX: Structure layers of metal carbide/-nitride: M 2 X, M 3 X 2, M 4 X 3 Monatomic layers of A-elements between Nano-Laminates:
6
Metals Ceramics MAX-Phase: MAX: Properties Machinable, electronic conductivity, ductile at high temperature, thermal shock resistant, rather low weight, chemical stability, heat resistant.
7
Metal Carbide /-Nitride Layered structure Properties Strong covalent M-X bondings: Good thermal, elastic, chemical & electrical properties. Relatively weak M-A bondings: Anisotropic mechanical properties, especially deforming mechanisms.
