| Abstract: | Cracking reasons of steel pipes for 480QZ automobile drive shaft are researched through the chemical composition analysis, mechanical testing, macro and micro fracture analysis and metallographic examination. It turns out that the martensitic structure in the weld zone of the shaft tube and the surface stress concentration of the weld toe lead to the fracture of steel pipes. |
