Studies photomicrographs and performs microscopic examinations on samples to determine metal characteristics, such as crystal structure, porosity, and homogeneity. Interprets findings and prepares drawings, charts, and graphs for inclusion in reports for reference or instruction purposes, and writes reports regarding findings, conclusions, and recommendations. Coordinates and participates in performing special tests, such as end-quench hardenability, bend and tensile, and grain size tests.
