Abstract

In this work, the age-hardening behavior of cast Al-Si base alloys was investigated. It was found that multiple aging peaks are present in the age-hardening curves of Al-Si-Cu-Mg alloys. TEM observations reveal that the age-hardening behavior is related to the precipitation sequence of the alloy. For the Al-Si-Cu-Mg alloy, the first aging peak is the result from the high-density GP zones, while the subsequent are from metastable phases. The transition from GP zones to metastable phases may be the main reason of the formation of multiple aging peaks.
