Abstract
The static recrystallization and precipitation behavior of weathering steel were studied using thermal simulation technology. The influence of temperature and interval time was analyzed and the softening percentage of static recrystallization was calculated. The morphology and distribution of precipitates were studied, and the driving force for static recrystallization and pinning force of precipitation were calculated. Results show that the higher the deformation temperature is, the faster static recrystallization proceed. Retardation of recrystallization could occur even in the early stage of precipitation. The precipitation pinning force showed a peak in the intermediate stage, and finally decreased as particles coarsened.
