:
perlita globular
- When iron cools extremely slowly, globular pearlite may develop instead of the usual lamellar structure.
Examples
-

Synonyms
A structure in steel where hard pieces form small round groups instead of layers from very slow cooling

Morphology
The meaning is directly compositional: 'globular' (spherical) modifies 'pearlite' (a steel microstructure), so the phrase denotes pearlite that has a rounded/spherical form. Although the term is technical, the adjective+noun composition follows ordinary English patterns, so a learner who knows both constituent words can infer the MWE meaning.
Etymology
Globular pearlite is a name for a steel pattern where globular means 'round' and pearlite is the mix of soft and hard parts that usually makes thin 'layers'. When steel cools very slowly, the hard parts form tiny round 'globules' like little 'pearls' instead of 'layers'. So globular pearlite describes this round, slow-cooled structure and shows the metal cooled slowly and will behave differently.
