The microstructures, mechanical properties and electrical resistivity have
been evaluated for deformation processed Al-20 vol % Mg and Al-13 vol % Mg
composites. The Mg second phase adopts a convoluted, ribbon shape filamenta
ry morphology after deformation. Both the size and spacing of these filamen
ts decreases with deformation. The strength of these composites increases e
xponentially with reduced spacing of Mg filaments. The electrical resistivi
ty of these Al-Mg composites is slightly higher than that of pure Al. (C) 1
