摘要
The precipitation of an AA2618 Al-Cu-Mg alloy is monitored during isothermal holdings and continuous coolings. The Time-Temperature-Property and Continuous-Cooling-Precipitation diagrams of AA2618 are obtained using in-situ resistivity and differential scanning calorimetry respectively. The two precipitation domains observed at high temperature and low temperature (< 300 degrees C) are discussed with regard to their influence on the mechanical properties during quenching of large components.
