DOI: 10.1016/j.ceramint.2016.11.074

Abstract: Abstract In this study, lamination as extrinsic mechanism was considered to enhance damage tolerance of three-layer Al6061-5%vol. SiC p /Al1050/Al6061-5%vol. SiC p composites. To fabricate laminates of dissimilar interfacial adhesion, different rolling strains were applied… read more here.
