Residual Stress Measurements via Neutron Diffraction of Additive Manufactured Stainless Steel 17-4 PH
Post, August 7, 2026 • (Harvard University) Neutron diffraction was employed to measure internal residual stresses at various locations along stainless steel (SS) 17-4 PH specimens additively manufactured via laser-powder bed fusion (L-PBF). Of these specimens, two were rods (diameter = 8 mm, length = 80 mm) built vertically upward and one a parallelepiped (8...
