MTech thesis. PDF 1357Kb: Abstract. Fe-6.67 wt. %C and Fe-1 wt. %C powders were milled in a dual drive planetary mill for 40 h. It has been found that there is a formation of Fe3C and other iron carbides after 40 h of milling. However, the formation of iron carbide is more in the case of Fe-6.67 wt. %C as compared to Fe-1 wt. %C.
