N) precipitation in ferrite of micro niobium HSLA steel and calculated NbC nucleation radius
nucleation rate and growth rate in ferrite with 900 ~ 1200 ℃. austenization are presented. The test results by some authors indicated the precipitation of niobium carbo-nitride needed higher dislocation density and the amount of NbC formed in ferrite was relatively minor as compared with that formed in austenite; and the tensile strength of steel sheet with coiled at 680 °C was obviously higher than that of sheet without coiled direct cooling to room temperature.
