摘要
Supersaturated solid solutions Fe_ 1-xC_x (0≤x≤0.9) of wide composition range have been prepared by mechanical alloying process. Nanocrystalline phase was formed for 0≤x≤0.67 and a large grain phase for 0.75≤x≤0.9. The large fraction of graphite volume puts off formation of nanocrystalline phase for...
