摘要：Austempered ductile iron （ADI） with high-strength and high toughness was created by method of austempering in the 1970s, which is characterized to have a tensile strength over 1000MPa, and an elongation more than 15%. With an orthogonal test and the method of austempering, the effect of the austempering technics on the microstructure and hardness of austempered ductile iron was discussed. It is found that austempered ductile iron which microstructure contains bainite and retained austenite can be gained in all of the designed austempering technics through the experiment. The hardness of samples could be mostly affected by the temperature of austempered, followed by the austenitizing temperature and austenitizing time, and the timing of austempering is proved to have the least influence on the hardness of samples.
