| Abstract: | This paper briefly describes the development status and material requirements of the fracture splitting connecting rod,compares the differences of the metallographic structure and alloying elements between the medium carbon non-quenched and tempered steel 36MnVS4 and 46MnVS5,discusses the causes of the defects such as the uneven fracture of 36MnVS4 connecting rod,and analyzes the influence of the alloying elements content on the properties of the new fracture splitting connecting rod material 46MnVS5.The results show that 46MnVS5 has better mechanical properties in yield strength,tensile strength and hardness,and the distribution of micro structure components is more uniform.Finally,the paper suggests the development trend of the forging technology of the fracture splitting connecting rod. |
