为研究钢筋混凝土在耦合盐环境中的腐蚀劣化规律及寿命分布，将钢筋混凝土试件置于0.32 mol·L−1NaCl和0.4 mol·L−1MgSO4盐溶液中，利用电化学工作站定期无损检测，以极化曲线、交流阻抗图谱及电化学参数指标进行耐久性分析，选择3参数Weibull进行可靠性建模，通过Anderson-Darling法（A-D）进行先验假设检验，采用相关系数优化法(CCOM)、极大似然法(MLM)及矩估计法(MEM)进行参数估计，综合可靠度曲线、密度曲线、失效率曲线对钢筋混凝土在氯盐、硫酸盐、镁盐腐蚀环境中的寿命进行分析

利用干湿周浸加速腐蚀实验对比研究了低合金钢A588和SPA-H在含氯离子环境下腐蚀行为,并利用金相显微镜、扫描电镜、X射线衍射和电子探针等方法分析了Ni、Mn对于低合金钢腐蚀行为的影响.结果表明:实验钢锈层中的物质主要由α-FeOOH、γ-FeOOH和Fe3O4组成,但其含量存在差异;Ni元素在内锈层含量高于外锈层,Mn元素在锈层的孔洞处富集;内锈层的致密程度高于外锈层;提高合金元素Mn和Ni的含量,可以提高内锈层的致密性,从而提高低合金钢的耐蚀性能

通过DIL805A热分析仪、扫描电子显微镜、电子背散射衍射、透射电子显微镜、力学分析等方法研究Mn对中锰耐磨钢组织形态、相变及力学性能的影响.随着Mn的质量分数以2%的增量从3%提高到9%,室温奥氏体含量逐渐增多,抗拉强度及硬度逐渐降低,抗拉强度和室温奥氏体体积分数都在5%到7%时变化明显,马氏体与奥氏体的位向关系发生改变,马氏体形态类型逐渐由亚结构以位错为主的板条状α马氏体变化为亚结构以位错、相变内孪晶和层错为主的束状细片α马氏体和细片状ε马氏体

选取商业纯铝和超硬铝作为锌电积阴极,在ZnSO4-H2SO4体系中通过电化学测试研究两种阴极的电化学行为,同时利用扫描电镜观察铝合金上电积锌初期形核,X射线衍射分析锌片结晶取向.研究结果表明：500 A·m-2电流密度下纯铝阴极的析出电位和交换电流密度分别为-1.541 V和7.74×10-11 A·cm-2,超硬铝阴极分别为-1.496 V和6.07×10-3 A·cm-2.合金元素的添加会增加初期形核位置,提高形核速率,而形核速率的提高在一定程度上抑制卤族元素对阴极的腐蚀.沉积3 h后,锌片结晶取向没有发生变化.超硬铝易发生烧板和鼓泡,电流效率低,只有84.54%;纯铝电流效率达到88.04%,且沉积锌平整、光滑,但阴极板容易被卤族元素腐蚀

以退火纯铁粉末为原料,采用粉末退火结合高速压制技术的方法制得高密度压坯(7.70 g·cm-3),经烧结后获得高密度高性能的纯铁软磁材料.研究退火粉末的高速压制行为,以及烧结时间和烧结温度对材料磁性能和晶粒大小的影响.结果显示:退火粉末的压坯密度随压制速度的增加而增加,压坯密度最高可达到7.70 g·cm-3,相对密度可达到98.10%.烧结温度为1450℃,烧结时间为4 h时,材料密度达到7.85 g·cm-3,相对密度为99.96%,最大磁导率达到13.60 m H·m-1,饱和磁感应强度为1.87 T,矫顽力为56.50 A·m-1
