Gradient Residual Strain Measurement Procedure in Surface Impacted Railway Steel Axles by Using Neutron Scattering

High-speed railway S38C axles undergo surface induction hardening for durability, but are susceptible to fatigue cracks from foreign object impact. The neutron diffraction method was employed to measure the residual strain in S38C axles, obtaining microscopic lattice distortion data, for the gradien...
