Abstract

Al-4.5%Mg alloys with varying amounts of Manganese, Chromium and Iron were unidirectionally solidified. The effects of the volume fraction and the size of the second phase, and dendrite arm spacing on the fracture toughness of those alloys were examined with the instrumented charpy impact test. Crack initiation energy decreased with the size of second phase and crack propagation energy decreased with the volume fraction of second phase. The needle shaped second phase than polygonal one decreased greatly absorbed energy. Absorbed energy increased with dendrite arm spacing because the deflection of the specimen increased with dendrite arm spacing.
