Highlights TiN was in-situ synthesized by laser powder bed fusion under different N 2 + Ar atmosphere. TiN/Ti gradient layered structure composites show high strength and ductility. Gradient layered structure Ti composite exhibits periodic changes in hardness of Ar and N 2 region. Hetero-deformation induced strengthening enhances performance of layered structure Ti composites.
