Granular pearlite is a common term used in metallurgy to describe a type of microstructure that forms when steel is cooled slowly from a temperature above its critical range. Some synonyms for this term include lamellar pearlite, banded pearlite, and spheroidized pearlite. Lamellar pearlite refers to the elongated shape of the pearlite microstructure, while banded pearlite describes the alternating layers of ferrite and cementite that make up the microstructure. Spheroidized pearlite is a type of granular pearlite where the cementite particles have transformed into a more globular shape, resulting in a more uniform and rounded microstructure. These synonyms are often used interchangeably depending on the context and the specific characteristics of the steel being described.
