Research on reducing a sound and mechanical properties of alloys of systems Al-Zn-Mg and Al-Zn-Mg-rare-earth metals and optimization of their structures

The comparative estimation of influence of the additives of alloys of system shows Al-Zn-Mg gadolinium and itterbium, that the additives of rare-earth metals render beneficial effect on reducing a sound and mechanical properties of aluminium alloys containing in the structure zinc
