Abstract
Texture evolution of as-extruded near eutectic Al–Si–Mg alloy with minor addition of Zr or V was studied by electron backscatter diffraction (EBSD), and the tensile properties were tested. To some extent, addition of 0.1% Zr could impede the recrystallization operation of near eutectic Al–Si–Mg alloy during hot extrusion. Addition of 0.1% V exhibits very strong inhibitory effect on recrystallization, that the texture of 4# alloy is mainly composed of deformation texture component of Brass {110}〈112〉, which may contribute to the excellent combined properties of ultimate strength (UTS), yield strength (YS) and elongation. The impact of Zr addition on the tensile properties is not as considerable as that of V addition.
