Abstract
The origin of microstructure within the heat affected zone (HAZ) of precipitation strengthened aluminum alloys was discussed. Detailed characterization and microstructural simulation using a phenomenological model were performed to ascertain microstructural evolution within the HAZ of alloy 2219-T87. It was found that microstructural modifications within the HAZ involved alterations to the size distribution and number density of θ' precipitates. At positions experiencing moderate peak temperatures, a significant increase in the size of precipitates and substantial reduction in precipitate number density were observed.
