boundary plane distributions in a cold-rolled and annealed ferritic stainless steel were investigated by means of EBSD techniques. The results show that, following cold rolling with the thickness... distributions are observed. The free energy reduction of the system is most likely attributed to the selective growth.Key words:grain texture; grain boundary plane; EBSD; ferritic stainless steel......
Electrodeposition of Fe-Ni alloy coating on ferritic stainless steel GENG Shu-jiang(耿树江), LI Yan-dong(李言栋), XIANG Dong(向 东), ZHOU Shi-gang(周时刚) School of Materials and Metallurgy... _____________________________________________________________________________________________________ Abstract: Fe-Ni alloy coatings were electrodeposited on ferritic stainless steel (FSS) in solutions containing FeSO4 and NiSO4. The effects of pH, [Fe2+]/[Ni2+] (molar ratio) of electroplating solutions......

and inclusions in Sn-bearing ferritic stainless steel were observed,and the relationship between the workability and the microstructure of the steel was established.Energy-dispersive X-ray spectroscopic... the tensile strength and the plastic strain ratio and also improves the plasticity with increasing temperature.A mechanism of improving the workability of ferritic stainless steel induced by Sn addition......
of cerium addition on the isothermal oxidation behavior of 00Cr17 NbTi ferritic stainless steel was studied at temperature up to 1,000 °C for 100 h in air. The results show that cerium additions can reduce the grain size of this ferritic stainless steel, improve the diffusion of chromium and decrease the critical concentration of chromium to form protective Cr2O3 layer. With the increasing......
Nb对0Cr11铁素体不锈钢组织和性能的影响颜海涛1,毕洪运2,李鑫2,徐洲0(1.上海市上海交通大学材料科学与工程学院2.宝钢股份研究院,上海 201900)摘 要:铁素体不锈钢与奥氏体不锈钢相比具有成本低,热膨胀系数低和耐应力腐蚀等优点,所以被广泛应用到汽车排气系统,家用电器和建筑等领域.研究了不同的Nb含量对铁素体不锈钢显微组织和力学性能的影响.研究结果表明:Nb有细化晶粒的作用,随着Nb含量的增加,晶粒的平均尺寸减小;由于合金元素Nb和Ti的加入,形成了TiN,NbC和Fe2Nb析出相,其透射电镜观察结......

stainless steel with TiC additions were studied by theory and experiment. Using an "edge?to?edge matching" model, a 5.25 mismatch between TiC(FCC structure) and ferritic stainless steel(BCC structure) was identified, which met the mismatch requirement for the heterogeneous nucleation of 430 ferritic stainless steel. TiC was found to be an effective nucleation site for the formation of acicular......
退火温度对Nb+Ti双稳铁素体不锈钢织构的影响颜海涛1,2,毕洪运2,李鑫2,顾佳卿2,徐洲-2(1.上海市上海交通大学材料科学与工程学院2.上海市宝钢股份研究院)摘 要:利用电子背散射衍射技术(EBSD)研究了不同退火温度对Nb+Ti双稳铁素体不锈钢织构的影响.结果表明,随着退火温度的升高,α织构逐渐减弱,γ织构逐渐增强,当退火温度为920℃时,α织构基本消失,材料以γ织构为主.对再结晶织构的形成机制的探讨认为,铁素体不锈钢具有较强的γ织构归因于"定向形核"和"选择生长"共同作用的结果. 关键词......
