  1. MAX-Phase Materials High performance ceramic materials for use in space applications Ida Kero Department of Engineering materials Luleå University of Technology

  2. Introduction MAX-phase Structure Properties My project

  3. MAX-Phase Ternary Carbides / Nitrides Family formula: Mn A Xn-1 M= Early Transition Metal A= Elements from Group 12-16 X= Carbon or Nitrogen

  4. MAX: Structure Nano-Laminates: Monatomic layers of A-elements between layers of metal carbide/-nitride: M2X, M3X2, M4X3

  5. MAX: Properties Ceramics Metals MAX-Phase: Machinable, electronic conductivity, ductile at high temperature, thermal shock resistant, rather low weight, chemical stability, heat resistant.

  6. Properties Metal Carbide /-Nitride Strong covalent M-X bondings: Good thermal, elastic, chemical & electrical properties. Layered structure Relatively weak M-A bondings: Anisotropic mechanical properties, especially deforming mechanisms.

  7. My Project Pure Bulk Ti3SiC2 Mechanical Properties Reaction Path Compare MAX-phases

  8. My Project Sintering Process: Vary: *Temperatures *Holding Times *Temperature Profile

  9. My Project Ord. Ball Mill Attritor Planetary Mill Milling Process: Main Risks: *Contamination *Agglomeration *Combine Mills *Vary Milling Time *Dispersants
