摘要: Abstract Residual stress evaluation is an important stage to interpret the fatigue behavior of many engineering materials. The present research aimed at evaluating non-destructively macroscopic compressive and balancing tensile residual stresses generated in surface layer core region, respectively, mechanically treated alpha titanium alloy Ti–2.5Cu. In order achieve that purpose, a combination energy-dispersive X-ray neutron diffraction was used. Results revealed zero-crossing depths (where value zero reached) distributions region were well defined.
