Bulk metallic glasses(BMGs) with new chemical compositions(ZrcoAgAlNi) were fabricated and the effects of Ag minor addition on the glass forming ability(GFA) and crystallization kinetics were studied. The x-ray diffraction(XRD) test was applied to identify the amorphousness of BMGs or possible crystalline phases. Using differential scanning calorimeter(Dsc), the thermal stability and crystallization kinetics under a non-isothermal condition at the different heating rates were studied. considering the heating rate dependency of glass transition and crystallization kinetics, the activation energy was evaluated and measured for the mentioned processes. It was revealed that the rise in Ag content led to the decrease in activation energy for glass transition, while the activation energy for crystallization increased. The thermal stability and GFA were also studied and it was found that the Ag addition strongly affected the inherent features of BMGs. With the increase in Ag content, the atomic mobility and structural rearrangement changed in the material and consequently, the GFA and thermal stability were significantly improved.

s5-1 Effects of persistent organic pollutants(POPs) in water on chongqing population health cAO Jia, TIAN Huan-Jun, sHU Wei-Qun(Preventive Medicine college, the Third Military Medical University, chongqing 400038, china)Abstract:Many organic pollutants occur in drinking water in considerable amounts, and mimic or interfere with reproductive development and function. Furthermore, it is not known whether multiple organic pollutants (MOP) from drinking water induce uterotrophic effects. In this study, we compared the effects of MOP on uterine wet weight by different exposure approaches (ip, sc, po) on prepubertal 21-d-old Wistar rats and Kunming mice. The multiple organic pollutants in drinking water were concentrated by solid-phase extraction (sPE), and dissolved in DMsO.

Multi- and unidirectional impact forgings were successfully applied to a （GW94） Mg-RE alloy. The microstructure and texture evolution were investigated systematically. The obtained results indicated that during unidirectional impact forging, a bimodal chain deform microstructure was sustained till last forging pass, whereas { 10-12} extension twins-assisted continuous dynamic recrystallization took place during the multidirectional impact forging （MDIF）. The coalescence and intersection of {10-12} extension twins during MDIF efficiently refined the original coarse grains and led to an almost recrystallized homogeneous microstructure. The texture analysis demonstrated that unidirectional impact forging yielded out the strong basal texture; however, MDIF resulted in non-basal texture, which was attributed to the cooperative effects of continuous DRX, twinning, and MDIF itself during the deformation process.
