| 1 | Aluminizing Low Carbon Steel at Lower Temperatures显示文摘This study reports the significantly enhanced aluminizing behaviors of a low carbon steel at temperatures far below the austenitizing temperature,with a nanostructured surface layer produced by surface mechanical attrition treatment(SMAT).A much thicker iron aluminide compound layer with a much enhanced growth kinetics of η-Fe2Al5 in the SMAT sample has been observed relative to the coarse-grained steel sample.Compared to the coarse-grained sample,a weakened texture is formed in the aluminide layer in the SMAT sample.The aluminizing kinetics is analyzed in terms of promoted diffusivity and nucleation frequency in the nanostructured surface layer. | Xiao Si Bining Lu Zhenbo Wang | 2009 | Journal of Materials Science & Technology2009，25，4： | 11 |
