SPU-6: Bubble Raft Education: Drew Davidson1; 1University of Florida
During the 1940s, Lawrence Bragg and J. F Nye created a new model to macroscopically demonstrate the dynamic model of a crystal structure known as a bubble raft. The bubble raft model is an array of bubbles on a soap solution that represent the atoms on the 111 family of a hexagonal close packed metal. These rafts have been used to examine dislocation motion on a bigger scale, but this has not been used as an educational tool in modern times with the most recent official video demonstration being done in 1952. Overall, the goal is to create a new array of videos on bubble rafts that can be used by educators to cover topics such as fault, slip, recrystallization, annealing, and strains.
SPU-7: Investigate the Effect of Crystallographic Orientation on the Mechanical and Corrosion Properties of Copper Single Crystals: Devin Davis1; 1University of North Texas
The main objective of this work is to investigate the effect of crystallographic orientation on the mechanical and corrosion properties of copper single crystals. Copper has unique microbial resistance and the material of choice for 2 Dimensional (2D) materials deposition for a wide range of applications. The lack of grain boundaries in a single crystal will minimize the defects in the 2D coatings and minimize the microbial corrosion. Single copper crystals were produced using Czochralski process, using process parameters such as rotational speed, crystal lift rate and melt temperature were optimized. It is believed that the differences in planar densities in various crystallographic planes would have an influence on both mechanical and corrosion properties. The mechanical properties of single crystals are evaluated using micro indentation technique and corrosion properties of the crystals are evaluated using electrochemical methods. The crystallographic orientation of the crystals was analyzed using XRD and EBSD techniques.
