investment and efforts in R&D as well as market-driven product strategies
(Osman et al. , 2006). A multitude of technical and cost barriers remain for
many of the inventions. For instance, concerns have surfaced about the
responsible development, production, use, and disposal of some nanomate-
rials and related technologies. These are generally sparked by the nanosize
effect and present unique challenges to be addressed before the successful
commercialization of nanocomposite steels in some applications. For
instance, Khettabi et al. (2008) indicated that the formation of nano- and
micro-sized particles during metal cutting may pose a health risk.
