Synergistic Effect of Alloying on the Strength and Ductility of High Carbon Pearlitic Steel

In this work, the effects of micro-alloying Mn, Ni, and Si on microstructure mechanical properties high-carbon pearlite steels were investigated. The results indicated that addition solely Ni to pearlitic steel can enhance strength through refinement interlamellar spacing, but work-hardening in ferrite colony may be delayed, leading a reduction area. multiple additions increase Mn contents beneficial obtaining balance between ultimate tensile Three-dimensional atom probe tomography showed partitioning into elements cementite. inhibited formation continuous network grain-boundary cementite, high ductility optimization microstructure.
