In this paper by means of TEM and HREM, we found that the presence of r-phase plays the most important role in enabling two way shape memory effect (TWME) to be obtained by the stabilization of stress induced martensite variants (SSIM). This idea is different from the traditional suggestion that str...

Preparation of carbon nanotube composite material with metal matrix by electroplating

Transactions of Nonferrous Metals Society of China

It is demonstrated that the nickel can be deposited directly on the surface of carbon nanotubes without pre-sensitization by Sn2+ and Pd2+ in a watt bath containing suspended nanotubes by electroplating. The nickel is deposited as spherical nanoparticle on the nanotubes. By increasing reaction time,...
