| Abstract Scope |
Al-Zn-Mg alloys are common structural materials used in building constructions for their high specific strength and good weldability. The limiting factor in the use of these alloys in welded structures is their tendency to exfoliation corrosion and to stress corrosion of both the base metal and especially the welded joint. Meanwhile there are some possibilities to improve stress corrosion cracking susceptibility by different approaches including heat treatment and microalloying. The influence of minor additives of transition metals, including rare-earth metals, on the mechanical properties and corrosion resistance of extruded semi-products and welded joints obtained by MIG welding was investigate. The present study also shows the influence of heat treatment conditions on the tendency to stress corrosion of extruded semi-products of Al-Zn-Mg alloys and their welded joints. It is shown that the balanced additives can lead to significant improvement in the characteristics of weld joints. |
