👉 In mathematics, a metallographist is someone who specializes in studying materials and their properties using the principles of mechanics, thermodynamics, and crystallography. They use these principles to analyze and understand how materials behave under various conditions, such as deformation, stress, and strain. Metallographists are often involved in research projects related to materials science, including materials engineering, metalworking, and aerospace technology. They use their expertise in mechanics and thermodynamics to design and fabricate experimental devices
