This paper is dedicated to studying the following fractional Kirchhoff-type equation (a+ b ∫ _ R^ N|(-\triangle)^ α/2 u|^ 2 d x\right)(-\triangle)^ α u+ V (| x|) u= f (| x|, u),\\x ∈ R^ N, a+ b∫ RN|(-▵) α/2 u| 2 dx (-▵) α u+ V (| x|) u= f (| x|, u), x∈ RN, where a, b> 0 a, b> 0, either N= 2 N= 2 and α ∈ (1/2, 1) α∈(1/2, 1) or N= 3 N= 3 and α ∈ (3/4, 1) α∈(3/4, 1) holds, V ∈ C (R^ N, 0, ∞)) V∈ C (RN, 0,∞)) and f ∈ C (R^ N * R, R) f∈ C (RN× R, R). By combining the constraint variational method with some new inequalities, we prove that the above problem possesses a radial sign-changing solution u_b ub for b ≥ 0 b≥ 0 without the usual Nehari-type monotonicity condition on f, and its energy is strictly larger than twice that of the ground state radial solutions of Nehari-type. Moreover, we establish the convergence property of u_b ub as b ↘ 0 b↘ 0. In particular, our results unify both asymptotically cubic and super-cubic cases, which improve and complement the existing ones in the literature.
