Abstract：
The strengthening mechanism,austempering process,microstructure characteristics and the effect of some technological factors on mechanical properties of ADI were introduced.The production,austenitization and isothermal transformation of ADI ductile iron blank were described in detail.The preparation technology and technical characteristics of noaustenitic ADI,two phase ADI,as-cast ADI and two-step ADI were described in order to provide theoretical basis for the production process and quality control of ADI products.
