以便调查分发 Cu 和 Mg ，和钢的 Cu 在微观结构的效果，分别地，包含各种各样的 Cu 内容的锰钢是退火的 at1260,1100 和 1000 °C 在 thefurnace 为 1 h 并且随后冷却了到房间温度模仿结果显示的 pre-rolling anneal.The 那 Cu 不是在观察显示出的退火的 steels.The 扫描电子显微镜学( SEM )的 microscopicallysegregated 那 themain 微观结构由铁酸盐和珠泽铁组成；
The corrosion behavior of low-carbon steel(CS),P-bearing steel(PS)and P-RE weathering steel(P-REWS)exposed for two years in Jiangjin of China was investigated.The results showed that during 2-year exposure test,corrosion data of the experimental steels followed the bilogarithmic equation,and the average corrosion depth of PS and P-REWS was decreased by 19.5% and 28.2% respectively compared with that of CS.Scanning electron microscope,electrochemical impedance spectroscope and Fourier transform infrared spectroscope were used to characterize the corrosion products.The research results showed that P in steel could promote the formation of an amorphous ferric oxyhydroxide layer near the substrate.The addition of RE could effectively increase the charge transportation resistance of rust.
