Abstract The microstructure formed during solidification has a significant impact on the mechanical properties of materials. In this study, two-dimensional (2D) cellular automaton (CA)-finite difference (FD)-CALPHAD model was developed to simulate formation and solute segregation in processes ternary alloys. model, dendritic growth is simulated using CA technique, while diffusion solved by FD method, CALPHAD method employed calculate thermodynamic phase equilibrium solidification....
Abstract Ti2SnC dispersion-strengthened (DS) copper matrix composites were prepared by the hot-pressing method. The change of microstructure, mechanical properties, and electrical resistivity as a function volume fraction studied. results demonstrated that grain size Cu decreased pronouncedly incorporating Ti2SnC, strengthening effect was significant. Improvements in yield strength up to four times pure found Cu-1 vol.% however, conductivity composite still 85.6% copper. high low indicated...

The motion paths of Balanus reticulatus cyprids were similar on all the titanium alloys surfaces. On parallel grinding surfaces, temporary attachment duration and settlement ratio influenced by roughness composition surfaces correlated positively. surface could also change contact area numbers points in pattern. Consequently, regulated cyprid duration. cross increased but drastically decreased to 0 compared grinding, possibly due voids drastic decrease surface, respectively. therefore...
