On mesoscale strain fluctuations in tensile tests on additively manufactured 17-4PH stainless steel
نویسندگان
چکیده
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 characteristic scale essentially independent probed processing parameters.

متن کاملLattice strain evolution during uniaxial tensile loading of stainless steel
Applied and residual lattice strains were determined by neutron diffraction during a tensile test of a weakly textured austenitic stainless steel and were compared to the predictions of a self-consistent polycrystal deformation model. Parallel to the tensile axis the model predictions are generally within the resolution of the diffraction measurements, but perpendicular to the tensile axis disc...
