| Abstract: | The reasons for the fracture of spiral spring were analyzed through observing the fracture morphology by means of scanning electron microscope,detecting metallographical microstructure,measuring the hardness,examining the quality of shot blasting and analyzing the chemical compositions of the material.The result shows that the spring has cracked before the test,and that a well controlled tempering condition can reduce the possibility of defects. |
