摘要：

The structure, age hardening response, precipitate type and hardness of A319 cast aluminum alloy without and with zirconium addition were investigated. The as-solutionized and artificially-aged hardness values were higher for the Zr-containing alloy. This is believed to be a consequence of the precipitation of Al(3)Zr particles produced during sufficiently long solutionizing treatments. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd.
