To improve the corrosion resistance of magnesium alloys, laminated material coated with aluminum alloys on the surface of AZ31 magnesium alloy, using titanium sheet as inserted material, has been developed by solid-phase diffusion bonding in vacuum hot pressing. After vacuum hot pressing, laminated materials were applied hot rolling to increase bonding strength. The bonding strength of laminated materials fabricated was examined by tensile shear test. The optimal maximum shear stress was 7 MPa at a bonding temperature 623 K, under applied stress 20 MPa and a bonding time 3.6 ks. Bonding strength is influenced strongly by the bonding temperature and applied stress. The mechanical properties of laminated materials were investigated by tensile test, bending test and conical cup test. As results of these tests, developed laminated composite materials were confirmed to have excellent plastic formability properties.
