LIU Jun-feng, JIANG Wen-yong, WANG Chen, et al. Effect of Nb on the Microstructure and Properties of ZG1Cr10MoNiVNbN Steel[J]. 2019, 24(1): 99-102.DOI: 10.15938/j.jhust.2019.01.016.
Abstract:In order to study the Nb alloy elements onZG1Cr10MoNiVNbN brand of the influence of the microstructure and mechanicalproperties of heat resistant corrosion resisting steel
through metallographicobservation
tensile
impact test and electrochemical corrosion
and get the Nbelement to this grade of steel mechanical properties and corrosion resistanceare studied The results show that when the content of Nb element is 015%
thestrip microstructure in the steel is finer and the carbide distribution is moreuniform The yield and tensile strength of the steel with Nb content of 015%were 8641 and 9857MPa
the elongation at break and the impact work were 144%and 269J
In corrosion resistance
written born current density and corrosionpotential were 31254E7A/cm2
