Morphology
The meaning is directly compositional: 'metallographic' relates to the microscopic analysis of metals and 'specimen' means a sample, so a learner who knows both constituent meanings can infer this is a metal sample for microscopic examination. Although technical, the term's internal structure is transparent and follows predictable English morphology, making it understandable to someone familiar with the components.
Etymology
Metallographic specimen is a name for a small metal specimen that lab workers grind, polish and etch so its inner parts show like a clear 'picture' under a microscope. That's why the term means a prepared metal sample used to study its 'structure'.
