Project Description: The disruptive potential of additive manufacturing relies on its ability to make customized products with considerable weight savings through geometries that are impossible/difficult to produce by conventional methods. However, poor repeatability of the additive manufacturing process is the major obstacle to its widespread use, especially for critical load-bearing metallic structures. This is due to extremely high heating and cooling rates during the process, causing many far-from-equilibrium and highly dynamic phenomena that are extremely challenging to study. We have conducted several experiments using high-energy, high-speed x-rays to develop a fundamental understanding of the transient phase transformation during the additive manufacturing process. We are looking for motivated students to analyze the data and establish a correlation between printing process parameters and solidification pathway and microstructure of printed parts.
