“…Austempered Ductile Iron (hereinafter referred to as ADI) is isothermally quenched at different temperatures to achieve high strength, high toughness, high fatigue, and wear resistance in the field of mechanical engineering; it is regarded as a high-tech material [13] and has been widely and successfully used in aerospace, vehicles, ships, and heavy industries internationally. However, due to the similarity of its processing properties and forged steel, the lack of a unified national standard, and the large differences in the material of ADI materials produced by various manufacturers, in the use of traditional processing methods and tools to process ADI, the tool wear is serious, which is a more difficult material to machine, often using time-consuming and labor-intensive annealing and grinding processes [14,15].…”
