Description 33-36
This investigation is primarily aimed to examine the premature failure of a spring used in a fuel pump bracket assembly. Preliminary visual examinations along with detailed SEM studies are made on the damaged surface and fracture surface of the failed spring. In addition, microstructural investigations along with hardness measurements are carried out to understand the reason for the premature failure. Finally, it is concluded that improper heat treatment of the spring material is responsible for failure.
