2Al5層,該層延緩了其在熱浸鋁過(guò)程的失效。鋼材的再結(jié)晶對(duì)于熱浸鍍鋁過(guò)程中界面金屬間化合物的影響包括:(1)再結(jié)晶可降低IMCS的形核和生長(zhǎng)能量,尤其是Fe4Al13相;(2)再結(jié)晶引起的晶粒沿密排方向排布可降低Al離子的擴(kuò)散速率;(3)再結(jié)晶加劇了IMCS/鋼界面處的應(yīng)力失配,尤其是奧氏體鋼。;The influence of steel's recrystallization on the stability of intermetallic compounds (IMCS) layer was investigated in molten Al at 700 °C. Results show that high degree of structural rearrangement leads to the formation of non-protective IMCS layer on the 304SS surface and its corrosion kinetics coincides with linear law. Compact and stable Fe2Al5 layer delays the failure of the 410SS in liquid Al. The stability of IMCS is affected by steel's recrystallization in three aspects: (1) energy for IMCS nucleation and growth are reduced, especially for Fe4Al13; (2) grain orientation transforms to close-packed direction which slows down the diffusion rate of Al ion; (3) stress mismatch is increased at the IMCS/steel interface, especially for the austenitic 304SS."/>
