%X Unhealed porosities and free surface of dendrites with crystalline steps were occasionally observed in aluminium alloy forgings. It was found that the dendrites grow preferentially along <100> directions and the crystalline steps belong mainly to {100} and {110} planes.In the neighbourhood of the unhealed porosities the alloy matrix appeared to be embrittled and in certain cases cleavage fracture was observed.
