Abstract
The precipitate percentage and the spheroidization percentage were analyzed as a function of the tempering temperatures and the alloying elements for high strength preheat-treated steel. The optimum temperature of tempering produced the small precipitates of nano size. The precipitate percentage and the spheroidization percentage were increased with the tempering temperatures. The size of precipitate decreased as the spheroidization of carbon precipitates progressed. The alloying elements such as Cr and Mo reduced the sphereidization temperature.
