Any realistic model will have high complexity; in other words, it will require many state variables to be adequately described. The resulting complexity, i.e. number of first-order differential equations, is such that a simplification or model reduction will be needed in order to perform a simulation in an amount of time which is acceptable for the application at hand, or for the design of a low order...

The thermal stability of aluminised coatings on Fe-alloys containing Ni, Si and Cr and of chromised coatings on Fe-alloys containing Ni and Si has been studied. The results indicate that thermal stability is affected mainly by phase equilibria and diffusion paths have been plotted on the appropriate ternary diagrams.
The oxidation of aluminised coatings on Fe Ni, Fe Si and Fe Cr alloys and of chromised coatings on Fe Ni and Fe Si alloys were studied at temperatures in the range 700 to 1000 o C and at oxygen pressures from 10 -8 to 1 atm. and related to appropriate phase diagrams. Up to 800 o C Al 2 O 3 or Cr 2 O 3 scales were formed leading to good...
