Morphology
The phrase is a straightforward ADJ + NOUN composition: 'metallographic' specifies the type of analysis (microscopic examination of metal structure) and 'sample' denotes a portion taken for study, so the meaning 'a sample for metallographic examination' is directly derivable. This compositional pattern is regular and transparent for learners who know both constituents, even if the term is technical.
Etymology
Metallographic sample comes from the parts metal, meaning the material, and graphic, from a word meaning 'to draw' or 'picture', so it literally means a metal piece made to show a picture of its inside. That's why a metallographic sample is a carefully prepared small piece of metal you look at under a microscope to study its inner structure.
