Cyberinfrastructure Needs

For LCF Information:

  • Upload capability for mechanical behavior strain-life fatigue curves, cyclic stress-strain reponse and monotonic stress strain results.
  • Upload capability for initiation pore size, average cell size, precipitate morphology and skin thickness - linked with above results.

For solution treatment and age hardening models:

  • Upload capability for beta phase dissolution and percipitate size and morphology as a function of solution treatment and age hardening parameters.

From ESPEI within CI.

  • Phase fraction calculation from ThermoCalc based on user-defined ThermoCalc database.

For IHTC

  • Upload and download capability for IHTC

Indication of provenance of all data above

Glossary of terms and agreed definitions (where does this go?).

Expected inputs

  • Predicted volume fraction of beta phase vs solidification time (TU)
  • Measured diffusion rates of Al and Zn in Mg (from Nagraj)
  • Databases of precipitate size vs aging time/temperature (from UofM)

Expected outputs

  • Algorithm for precipitate size and volume fraction vs aging time and temperature
  • Model for YS and strain-life curves

Interactions with CI

  • download thermodynamic equilibria, Gibbs energy and diffusion data from CI after the data is available
  • Quantitative precipitate characteristics for AZ 91 from UofM
  • As-cast microstructure prediction from Tsinghua
