| 1 | Microstructural characterization of silicon carbide reinforced dissimilar grade aluminium explosive clads显示文摘Aluminium composites are inevitable in ship building,commercial and defence aircrafts construction due to their light weight,high strength to weight ratio,admirable properties and cost affordability.In this study,the microstructural characteristics of explosive cladded dissimilar grade aluminium(Al 1100-Al 5052) clad composites reinforced with silicon carbide(SiC) particles is presented.Microstructure taken at the interface by optical and scanning electron microscopes(SEM) revealed the formation of a silicon carbide layer between the dissimilar grade aluminium sheets.Though reaction layers were witnessed at few locations along the interface,the diffusion of atoms between the participant metals is not visible as confirmed by energy dispersive spectroscopy,elemental mapping,line analysis and X-ray diffraction(XRD).The variation in microhardness at various regions of the silicon carbide reinforced dissimilar aluminium explosive clad is reported.The increase in tensile strength of the SiC laced clad is also presented. | S.Saravanan H.Inokawa R.Tomoshige K.Raghukandan | 2020 | Defence Technology(防务技术)2020，16，3： | 2 |
