摘要：

In this study the influences of predeformation and heat treatment conditions on stress-induced melt activating process (SIMA)of A319 aluminum alloy were investigated. At 30% of predeformation a dominant globular structure of grains was obtained. However, further increasing of the predeformation rate considerably reduced the shape factor. The holding time of 10-15 min at semi-solid temperature of 580 degrees C was suggested in order to prevent.-rain growth. Coarsening of the grains by excess time or temperature of heat treatment reduced the tensile strength of the alloy. (C) 2008 Elsevier B.V. All rights reserved.
