Abstract
One embodiment of the present invention discloses a member for automobile structure including a base steel sheet and a plating layer covering at least one surface of the base steel sheet, wherein the member for automobile structure has a tensile strength of 1350 MPa or greater and a yield strength of 900 MPa or greater, wherein the base steel sheet includes a martensite phase having an area fraction of 80% or greater, an iron-based carbide located inside the martensite phase and having an area fraction of less than 5% based on the martensite phase, and precipitates distributed inside the base steel sheet, wherein a mismatch dislocation exists at the interface between iron and the precipitates of the base steel sheet, and a difference between lattice constants of the iron and the precipitates is less than 25% of the lattice constants of the iron.
