Mechanical Properties of 3.45 wt.% Si Solution Strengthened Ferritic Ductile Iron at Room and Low Temperatures: Microstructure and Tensile Properties

  • Published:
Strength of Materials Aims and scope

The challenges of the 21st century require developing new materials combining attributes such as low cost, high strength and toughness, machinability, and recyclability. This is particularly true for alloys that are produced in mass, such as cast irons. Solution-strengthened ferritic ductile iron (SS-FDI) is a promising candidate to become a strategic material that summarizes the abovementioned attributes. The microstructure and static strength at room and low temperature (–25°C) of a 3.45 wt.% Si SS-FDI were investigated. The results showed that the analyzed cast iron is a promising material that, compared to traditional cast iron grades, shows a unique favorable combination of high strength and elongation at rupture.
