الملخص

The effect of different shot peening time (SPT) on the rotating bending fatigue behaviour of austenitic stainless steel TP321 was studied. The fatigue improvement with respect to the unpeened condition was discussed. Shot peening treatments employing steel balls determine a remarkable increment of the high-cycle fatigue limit of austenitic stainless steel ranging between 4% and 15% . such improvement can be essentially attributed to the compressive residual stresses deduced by the treatment in the surface layers . While the life improvement factor (LIF) was increased by a factor ranging between 1.72 to 5.3. All these improvement were happened up to 20 min shot peening time (20 SPT).
