A forging process can lead to material's micro- and nano-structure evolution, as well as production of internal residual stresses (RS). Typical fine-grained microstructures are achieved after forging at different temperatures, which are usually investigated and interpreted via conventional tests and analyses including optical, scanning and transmission of electron microscopy. The outputs from these methods can present an important lack of data, regarding basic parameters that aid comprehend and eventually predict degradation, possible fracture and lifetime. These parameters are determinable on real samples and can be supplied by neutron-based non-destructive diagnostic methods, in particular small angle neutron scattering (SANS) for micro- and nano-scale characterisation and neutron diffraction (ND) to assess internal RS. In this paper, some examples related to forged components - in particular, made of AlSi12CuNiMg alloy - are reported, concerning investigations by neutron techniques. The result can be translated directly into optimization of performances, reliability, design of operating conditions and procedures, in order to achieve a better quality of forged products.
