Microstructure and mechanical properties of spray-deposited ultra-high carbon steel after hot rolling

摘要

The tensile mechanical properties of as-cast ingot metal (IM), spray-formed (SF), and as-hot-rolled (HR) ultra-high carbon steels (UHCS) containing silicon were investigated in this paper. The relationship between microstructure and tensile properties was described for these steels. The carbide networks, the pearlitic interlamellar spacing, the size of carbide particles, and the volume ratio between lamellar and spheroidized structure are all microstructure factors influencing the tensile properties in UHCS.
