Abstract:  
The ZT TRW branch in Lafayette, Indiana produces power steering systems for the heavy-duty trucking industry. To meet performance and safety standards for their customers, ZF TRW uses shot peening to increase the fatigue life of their products. Mark Herter, Program Manager with ZF TRW, engaged the services of the research team with Purdue Materials Engineering to provide guidance on which parameters are the most important in the shot peening process and how modifying these parameters affects the microstructure, residual stress, and hardness.
