摘要：
This paper presents preliminary results on the mechanical and corrosion properties of a Fe-2Si-0.1C-0.1Nb dual-phase ferrite martensite (DFM) steel embedded in concrete. Previous research has shown that these steels can attain higher tensile strengths, higher energy absorption, more ductility, better fatigue toughness, weldability, and better corrosion resistance than conventional reinforcement (re-bar) steels. This investigation show that Fe-2Si-0.1C-0.1 Nb DFM steels with approximately 18% martensite volume, when embedded in small concrete beams and subjected to an accelerated corrosive environment, are more resistant to corrosion than standard billet reinforcement and may offer considerable potential as a new economical steel for concrete reinforcement.
