Abstract
The microstructures of powder metallurgy steels are typically pearlitic in the as-sintered condition or martensitic after-heat treatment (quench-hardening or sinter hardening). By design of the alloy system, a bainitic microstructure can be produced in a powder metallurgy steel after sintering. In the wrought ferrous industry, bainitic steels are known to exhibit high strength and hardness and a high level of toughness. The aim of this research was to develop a bainitic microstructure in a powder metallurgy steel with a high level of strength and toughness and acceptable ductility. The study focused on alloy composition and attendant mechanical properties and microstructure. In addition, processing routes were examined to achieve bainitic and mixed (pearlitic/bainitic/martensitic) microstructures with the potential to enhance mechanical properties.
