Previous investigations dealt with the effects of build orientation and allowance for machining on the fatigue strength of DMLS produced Stainless Steel 15-5 PH1. Additional studies on Maraging Steel in the “as built” condition, highlighted the heat or surface treatments that are able to enhance the fatigue strength. This work deals with an extensive experimental campaign involving as fabricated 15-5 PH1: the effects of heat treatment, machining and shot-peening after machining have been assessed. The retrieved S-N curves have been compared by statistical methods, highlighting the beneficial effect of the post-machining peening treatment.

Abstract
Previous investigations dealt with the effects of build orientation and allowance for machining on the fatigue strength of DMLS produced Stainless Steel 15-5 PH1. Additional studies on Maraging Steel in the “as built” condition, highlighted the heat or surface treatments that are able to enhance the fatigue strength. This work deals with an extensive experimental campaign involving as fabricated 15-5 PH1: the effects of heat treatment, machining and shot-peening after machining have been assessed. The retrieved S-N curves have been compared by statistical methods, highlighting the beneficial effect of the post-machining peening treatment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
