Research, Production and Application of High Strength Rebars
Abstract:
The paper reviewed the research, production and application of V - N microalloyed high strength rebars in China. Enhanced - nitrogen in V - containing rebars promotes precipitation of fine V( C, N) parti cles, and improvesmarkedlyprecipitationstrengtheningeffectivenessof vanadium. Therefore, V addition in V - N rebars can be reduced by 40 % compared with the same strength level of V - containing rebars. VN microalloyed technology is a cost - effective way for the development of high strength rebars inChina.
Keywords:
high strength reinforcing bars; V - N microalloyed; precipitation strengthening.
