The weathering steel with N-V micralloying is produced in a vacuum induction furnace.The microstrueture was analyzed by metallographic microscope and TEM,and the strength and toughness of experimental steel is characterized by tensile test,impact test and fracture analysis.The results show that the low carbon weathering steel with N-V microalloying has excellent plasticity and high strength and toughness.The microstrueture consists of equiaxed ferrite and a small amount of aberration pearlite(5% volume fraction)as well as similar granular bainitie formed in part of ferrite grain(30% volume fraction).Fine ferrite grain is gained with N-V micoalloying and the average size of ferrite grain was 7.8μm since the disperse precipitation of VN particles.
