28.02.2014· Mechanical properties of the SFSP AZ31 magnesium alloy are much higher that those of the NFSP alloy, especially the ductility. The SFSP AZ31 magnesium alloy shows excellent formability with an elongation of 50.5%, which is twice higher than that of the BM.
However, differences in physical and metallurgical properties of these two alloys presents challenge to join the 316L steel and AZ31 magnesium alloy using conventional fusion welding methods. Therefore, the use of liquid phase forming interlayers, which form a eutectic at temperatures lower than the melting point of steel and magnesium alloys, could overcome the differences in their physical
