%X The aging of a drawn eutectoid carbon steel with true strain 2.89 at different temperatures has been studied by means of TEM and electrical resistance measurement. The results indicated that the aging at 473K for 1hr improved the tensile strengths from 2245.65MPa of as-drawn to 2448.52MPa. Better mechanical property with combination of strength and ductility was observed after aging at 673K for 1h. Further increase of aging temperatures deteriorated the property possibly due to the recrystalization. The underlying mechanism of the better mechanical properties after aging at low temperature (673K) is considered to associate with the precipitation of fine carbide dissociated in the drawing.
