采用激光诱导击穿光谱法(LIBS)对不同工艺下的焊接接头根部中心区域进行了铜的深度分布分析,探讨了不同材料的LIBS激发脉冲数目与其剥蚀深度的相关性,发现在10个脉冲内脉冲数目与剥蚀深度有良好的一次线性关系,同样的脉冲数目激发焊材所得的剥蚀深度要小于铜衬垫,并由此计算了焊接接头根部中心部位渗铜区域的深度。同时,绘制了匹配的中低合金钢的定量分析校准曲线,并对不同渗铜区深度方向的铜含量进行了分布分析,发现不同工艺下的焊接接头的渗铜程度有较大差别:带铜垫脉冲控制工艺焊接的接头在某些区域出现了较为严重的渗铜现象,表面渗铜质量分数超过了0.5%,同时渗铜深度超过了50μm;铜垫短弧控制工艺焊接的SY2样品有少量渗铜,但表面渗铜质量分数均没有超过0.5%,且渗铜深度均不到10μm;而无铜垫脉冲控制工艺焊接样品SY3则表面没有出现渗铜现象。

在0.1mol/L盐酸中,铀可与显色剂偶氮胂Ⅲ迅速反应生成蓝色络合物,据此建立了分光光度法测定微量铀的方法。通过试验确定最大吸收波长为652nm,0.1mol/L HCl的加入量为500μL,500mg/L偶氮胂Ⅲ的加入量为2.0mL。结果显示,铀的质量浓度在0~4.0mg/L范围内符合比尔定律,其线性方程为A=0.248 99ρ-0.000 1,相关系数R2=0.999 8,表观摩尔吸光系数(ε)为5.93×104 L·mol-1·cm-1。对两个含铀废液按实验方法进行测定,相对标准偏差(RSD,n=5)为0.77%和0.51%;采用电感耦合等离子体质谱法(ICP-MS)进行对照试验,结果吻合较好。

Ferritic stainless steels are promising candidates for IT-SOFC interconnect applications due to their low cost and resistance to oxidation at SOFC operating temperatures. However, steel candidates face several challenges, including long term oxidation under interconnect exposure conditions, which can lead to increased electrical resistance, surface instability, and poisoning of cathodes due to volatilization of Cr. To potentially extend interconnect lifetime and improve performance, a variety of surface treatments were performed on AISI 441 ferritic stainless steel coupons prior to application of a protective spinel coating. The coated coupons were then subjected to oxidation testing at 800 and 850 degrees C in air, and electrical testing at 800 deg C in air. While all of the surface-treatments resulted in improved surface stability (i.e., increased spallation resistance) compared to untreated AISI 441, the greatest degree of improvement (through 20,000 hours of testing at 800 deg C and 14,000 hours of testing at 850 deg C) was achieved by surface blasting.

The research under this project focused on a theoretical and computational modeling of dislocation dynamics of mesoscale deformation of metal single crystals. Specifically, the work aimed to implement a continuum statistical theory of dislocations to understand strain hardening and cell structure formation under monotonic loading. These aspects of crystal deformation are manifestations of the evolution of the underlying dislocation system under mechanical loading. The project had three research tasks: 1) Investigating the statistical characteristics of dislocation systems in deformed crystals. 2) Formulating kinetic equations of dislocations and coupling these kinetics equations and crystal mechanics. 3) Computational solution of coupled crystal mechanics and dislocation kinetics.
