The interfacial microstructure evolution of 12Cr1MoV/TP347H dissimilar steel welded joints with a nickel-based filler metal during aging was studied in detail to elucidate the mechanism of premature failures of this kind of joints.The results showed that
Cu-graphene(Gr)composite thin films were prepared by electrodeposition route using in-house synthesized Gr sheets.The Gr sheets were synthesized by the electrochemical exfoliation route using 1 M HClO4 acid as electrolyte.The Gr sheets were confirmed by X
The present study focuses on interface microstructure and joint formation.AA6061 aluminum alloy(Al)and commercial pure titanium(Ti)joints were welded by ultrasonic spot welding(USW).The welding energy was 1100-3200 J.The Al-Ti joint appearance and interfa
Surface deterioration occurs more easily in nickel-rich cathode materials with the increase of nickel content. To simultaneously pre-vent deterioration of activ
