Abstract Components produced by additive manufacturing (AM) via direct metal laser sintering (DMLS) have typical as-fabricated surface defects. As a result, properties of AM products should be modified to increase their strength, anti-wear behavior, and at the same time ensure high corrosion resistance. Surface modification shot peening (SP) is considered suitable for engineering devices made 1...

Additively manufactured materials usually exhibit mesoscale heterogeneities. Mesoscale fluctuations of strain fields in notched samples made 17-4PH Stainless steel and loaded tension are investigated. Regularized digital image correlation enables for the analysis at different length scales. Five tests on specimen fabricated with printing parameters studied. It is shown that have no characterist...
