MatCalc 5.31

See the changes which happened with version 5.31 below



version 5.31.1005: online 2009-09-25

  • This version represents a major version change from 5.30.xxxx to 5.31.xxxx. The most important changes are listed below.
  • A new category of variables has been introduced denoted as GBB variables (Generalized (nearest-neighbor) Broken Bond) from the model published in [B. Sonderegger and E. Kozeschnik, „Generalized nearest neighbor – broken bond analysis of randomly oriented coherent interfaces in multi-component fcc and bcc structures“, Metall. Mater. Trans., 40A (2009) 499-510]. The most important of those is the Calculated Interfacial Energy (CIE) for planar, sharp interfaces and the atomic pair interaction parameters LIJ_INTER$El1$El2.
  • The GBB variables can now be used without taking magnetic interactions into account. In order to conserve compatibility with previous version, a new phase flag has been introduced which takes into account magnetic effects in GBB quantities just as before: By default, Phase status→ flags → GBB variables without magnetic contribution is not set. * WARNING * use this feature with some caution!
  • There was some restructuring in the variables categories in general.
  • The evaluation of precipitation strengthening has been improved by taking into account a critical coherency radius under which precipitates are cut and above which precipitates are bypassed by dislocations. New variables are available to facilitate evaluation of strengthening based on user-defined functions incuding the total number and mean radius of precipitates above and below the critical coherency radius.
  • Plots can now be exported into pdf files as they are, that means with correct font sizes etc.
  • It is possible now to define a log file, which traces the output window during your calculation and operation. Use the command SET_LOG_FILE with enabled/disabled.
  • The script menu has been extended and modified. It is possible now to quickly access user-defined and pre-defined scripts, which appear in the new 'script' menu. This menu displays scripts that are placed in the scripts/script_menu folder. These options are helpful, for instance, for quickly creating and arranging windows that are frequently used.
  • The RMB menu options 'Copy & close' and 'Execute & close' are now working correctly in the command-history window. These functions are convenient for developing scripts or execute commands from the command history.
  • A bug in the execution of post-segment-scripts in the heat treatments has been corrected.
  • The output message during precipitation calculations for '*** warning: *** error calculating maximum driving force (22x)' and '*** info: performed growth correction (17x) ***' are now displayed in grouped manner to increase readability of precipitation simulation output.
  • The commands for defining stepped calculations for T0-calculus in the MatCalc console are implemented now.
  • The treatment of interfacial energies has been slightly modified to eliminate the influence of the precipitate phase fraction.
  • This version contains several bug fixes from previous versions.
