  author={Gong Shi-hong},
The properties of anti-seismic φ25 mm HRB400 steel bar were systematically investigated. The results showed, comparing with 20MnSi steel bar, the properties of HRB400 are enhanced in terms of matching between strength and ductility, sensibility of strain aging, low temperature brittleness, weldability and high strain low cycle fatigue. TEM and electron diffraction observation showed that only a small part of little vanadium is existed as VN, and most are existed in pearlite as alloy cementite… CONTINUE READING
