AlMg alloys have been widely explored and used as light-weight structural material in automobile and aircraft. To optimize the strength and ductility of AlMg alloy, we used magnetron sputtering to fabricate epitaxial AlMg thin films with high density twinned structure. The microstructure evolution with the varying Mg composition has been characterized. The highest flow stress has been observed in AlMg thin film exceeds 700 MPa, as examined by nanoindentation and in situ uniaxial pillar compression test. The strengthening mechanisms related to the solid-solution and twin boundary are discussed.
