Abstract
Neutron Diffraction shows that plastic pre-deformation and heat treatments have opposite effects on the residual stress in Al– SiCp composites. The thermal micro residual stress is relaxed or even reversed by pre-strains above 0.2%, but restored by heat treatments. The sense of relaxation changes above 400 C (the mixing temperature).File in questo prodotto:
