Stainless steel 316 L powders with powder size of 150 nm and 5 μm were mixed with a binder with a water soluble component which consisted of a major fraction of water soluble Polyethylene Glycol (PEG), a minor fraction of polymethyl-methacrylate (PMMA) and some stearic acid has been used as a surfactant. This work aims to investigate the rheological properties of a feedstock which are efficiently characterised by capillary Rheometry to measure apparent viscosities at different temperatures and shear rates. Results obtained by the varying feedstock characteristics, when viscosity decreases by increasing of shear rate at certain temperature feedstock should have a pseudoplastic behaviour. Melt viscosity of the feedstock was decreased by adding Nano-scale powders. The reduced (n) values at high temperature with addition of nanoparticles indicated a possible increase in the shear-thinning behavior. 2014-06-02T08:57:33Z 2014-06-02T08:57:33Z 2013-08 Article Journal of Nano Research, vol. 23, 2013, pages 36-42 1662-5250 http://www.scientific.net/JNanoR.23.36 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35010 en Trans Tech Publications |
