metallography
This term refers to a specialized branch of materials science. It is used almost exclusively in technical, academic, or industrial contexts, such as metallurgy or quality control in manufacturing. It describes the process of preparing and examining a metal surface to reveal its internal structure.
As a field of study or a scientific technique, the word is uncountable. It describes a discipline rather than a discrete object, meaning it does not take a plural form in standard professional usage.
