| Outline of Final Research Achievements |
The purpose of this application is to enable the prediction of mechanical properties of the harmonic structure materials control using multivariate analysis (multiple regression analysis).
Effective parameters for the strength of harmonic structure materials were determined with experimental approach. Through this research, it is cleared the harmonic structure indicates extra hardening beyond Hall-Petch relationship. Three parameters were selected for multiple regression analysis which are average grain size of coarse grains, average grain size of fine grains and area fraction of fine grains. it was cleared that strength of the harmonic structure materials can be estimate via multiple regression analysis using those three parameters.
