摘 要：Precipitation-hardened aluminum alloys need to be heat treated to achieve the mechanical properties required for their *** production of these materials can be optimized to make them more attractive and competitive comparing to other materials such as composites that have a growing and large market share in aeronautics *** way to do this is by controlling the artificial aging of precipitation-hardenable aluminum alloys,such as the 2000 series Al-Cu *** alloys can be monitored in real time by analyzing their conductivity behavior inside the *** objective of this work is to evaluate the electrical conductivity behavior in real time of the 2024 alloy during the artificial aging at 190°*** this,analyses were made in order to assess the behavior of the microhardness curve by aging time and its microstructural characterization with thermal treatments in the times of 1 h to 9 h interrupted every 1 *** results of the electrical conductivity versus hardness curve showed a significant correlation and indicate that this measure has great potential to be used as a tool to control the thermal treatment of aging.
