Mgbe usoro isi oyi na-emepụta bolts isi oghere hexagon, nhazi mbụ nke ígwè ahụ ga-emetụta ikike ịkpụ ihe ozugbo n'oge nhazi isi oyi. Ya mere, ígwè ahụ ga-enwerịrị ezigbo plasticity. Mgbe ihe mejupụtara kemịkalụ nke ígwè ahụ na-agbanwe agbanwe, nhazi metallographic bụ isi ihe na-ekpebi plasticity. A na-ekwenyekarị na pearlite dị nro anaghị enyere aka ịkpụ isi oyi, ebe pearlite dị okirikiri nwere ike ime ka ikike ịkpụ plastik nke ígwè ahụ ka mma nke ukwuu.
Maka ígwè carbon ọkara na ígwè carbon ọkara nke nwere nnukwu ihe njide siri ike, a na-eme spheroidizing annealing tupu oyi agaa, ka e wee nweta pearlite spheroidized dị mma na nke dị mma iji mezuo mkpa mmepụta n'ezie.
