| Abstract: | The crankshaft materials with perfect comprehensive performances, such as high ductility pearlitic ductile iron （QT800-6/QT900-6） and ADI were presented, and their application prospects in turbocharged diesel engine crankshaft were analyzed. The results show that the strengthening QT800-6/ QT900-6 crankshafts with stable production process and good product consistency have a vast potential for future development. But due to no forming ADI crankshafts market and greater investment for specialized isothermal quenching heat treatment equipments, the development of ADI crankshafts is restricted greatly. |
