Study of the solidification structure of compacted graphite cast iron
International Journal of Cast Metals Research, 2016 AbstractThis investigation focuses on the study of the solidification mechanism of compacted graphite cast iron (CGI). The solidification macrostructure was revealed in cast samples using a special technique known as direct austempering after solidification (DAAS). The microstructure was revealed by colour etching.

The effect of Fe and Ni catalysts on the growth of multiwalled carbon nanotubes using chemical vapor deposition [PDF]
Journal of Nanoparticle Research, (2010), Vol. 12, pp. 457- 465, 2019 The effect of Fe and Ni catalysts on the synthesis of carbon nanotubes (CNTs) using atmospheric pressure chemical vapor deposition (APCVD) was investigated. Field emission scanning electron microscopy (FESEM) analysis suggests that the samples grow through a tip growth mechanism.
