In this study, two CCCT diagrams are drawn to be compared with a CCT diagram. The CCCT diagrams represent continuous cooling transformations in stress assisted state. The increased Md and Bd temperatures of CCCT diagrams were also compared with those of the CCT diagrams and the cause was investigated from both thermodynamic and metallurgical viewpoints. Thermodynamic examinations revealed that ...
Effective data warehouse design requires a conceptual modeling phase. This paper describes a data warehouse design method based on the conceptual, logical and physical levels. The conceptual phase creates an UML model. To this end, UML is enriched with multidimensional concepts. The logical phase maps the enriched UML model into a multidimensional one. The physical phase maps the multidimension...
Employing the Ginzburg-Landau phase-field theory, a new coupled dynamic thermo-mechanical 3D model has been proposed for modeling the cubic-to-tetragonal martensitic transformations in shape memory alloy (SMA) nanostructures. The stress-induced phase transformations and thermo-mechanical behavior of nanostructured SMAs have been investigated. The mechanical and thermal hysteresis phenomena, loc...
