 note = {application, The low carbon steels (S15CK) were carburized by pack carburizing, and then these steels were heat-treated for primary quenching and secondary quenching. The transformation of the mechanical properties and the microstructures with varing carburized depth and hardening processes were investigated. The strength properties were improved with increasing caburized depth, but the elongation and the reduction of area were decreased markedly as quenched into water and oil in secondary quenching. In the carburizing of 5 hours the maximum hardness of the case was seven times the hardness of material as quenched into water in secondary quenching. In the test piece for tensile test quenched into water and oil as secondary quenching the quasi-cleavage fracture was observed.},
