Abstract

Al-Mg-Sc-Zr alloys are attractive materials for aircraft and marine applications and
have very good potentials for mechanical property enhancement by ultrafine grain
structuring. The most developed technique for producing nanostructures has been
equal channel angular extrusion. In this paper we describe our attempts on refining
grain in these alloys by the twist extrusion technique. It was shown that twist
extrusion allows to obtain fairly homogeneous structure with grain sizes dav=0.33,
0.08, and 0.65 μm. This structure is thermally stable up to 500ºC for 1 hour.
