Pearlitic structure is composed of ferrite and cementite layer. The mechanical properties of pearlitic steel have been extensively investigated. Strength of pearlite steel is affected by microstructure such as interlamellar spacing, colony size, block size and prior-austenite grain size. However, influence of these microstructual factors on mechanical properties are not clear. In this study, tensile tests were conducted on several microstructure controlled pearlite steels. As a result, mechanical properties of pearlite steel were strongly affected by interlamellar spacing.
