| Abstract: | The raw material, the microstructure and the mechanical property of the imported 42CrMo quenched and tempered steel crankshaft were analyzed. The homemade 42CrMo quenched and tempered steel crankshaft blank was developed by referring to foreign quenched and tempered technology of forging crankshaft blank and doing heat treatment experiments of forging blank. The bending fatigue test, the durability test and the reliability test of test bench and vehicle after making crankshaft blanks into products prove that 42CrMo steel can be used by medium-bore high-speed diesel engine crankshaft. |
