The secondary phases may be another sympathetic nucleated lower bainitic ferrite plate or lower bainitic Carbide. 实验观察到下贝氏体碳化物在巨型台阶前沿奥氏体内析出，而并非在下贝氏体铁素体内析出。
The effect of austenitizing temperature on structure and properties of vanadium bainite ductile cast iron is studied in present research. 研究结果表明，钒使贝氏体转变所要求的奥氏体化温度范围增大，并使贝氏体球铁的硬度提高。
