Abstract
Cold drawn pearlitic steels posses a hierarchical microstructure consisting of pearlitic colonies (first microstructural level) and pearlite (ferrite/Fe & cementite/Fe3C) lamellae (second microstructural level) that evolves during the manufacturing process by cold drawing towards a preferential orientation aligned in the drawing (wire axis) direction, so that these materials acquire microstructural anisotropy that influences their posterior fracture behaviour. The paper establishes an analogy with the literature of Spanish writers Fray Luis de León and Miguel de Cervantes (through the alternate distribution of ferrite/cementite lamellae), as well as with the painters Maurits Cornelis Escher and Victor Vasarely (through the multi-level organization of their paintings) and the composer Johann Sebastian Bach (through the hierarchical structure of his music).
