Effect of VN Alloying on the Structure of 20MnSiV Concrete Steel
Abstract:
The microstructure and V-precipitate of 20MnSiV concrete steel through VN alloying and Fe-V alloying are studied. In 20MnSiV steel with VN alloying there are more ferrite and Jess pearlite; the amount of V-precipitate increased obviously. For 20MnSiV steel produced with VN alloying, higher yield strength and lower impact transformation temperature will probably be achieved.
Keywords:
concrete steel, microalloy steel; pro-eutectoid ferrite; pearlite; V-precipitate.
