The microstructures of the commercial aluminum heavily deformed by the accumulative rolled bonding (ARB), the equal channel angular pressing (ECAP) and the common cold rolling (CR) were determined by the electron backscatter patterns system in SEM with thermal field gun. It was found that the EBSP system can be used to determine the microstructure in the deformed state, even in the heavily deformed state. The local texture of the deformed materials was reveal also in this paper.

The influence of alloying design,controlled rolling technology and cooling system of X100 hot-rolled strips on microstructure and micro-hardness has been discussed in detail in this *** results show that optimal chemical composition range of X100 hot-rolled strips is obtained on the basis of X80 by increasing contents of C,Mn,Ni and Mo of *** granular bainite microstructure could be refined and the volume fraction and size of M-A islands could be controlled in a reasonable range by reasonably regulating cooling rate and coiling temperature of X100 pipeline steel,which ensure high strength and toughness of X100 pipeline steel.

在石油类污染水体中,油会吸附在悬浮颗粒物表面而形成一个双层结构,影响水体后向散射系数光谱特征,分离水体石油类物质与悬浮颗粒物对后向散射系数光谱的贡献,能提高水体石油类污染后向散射理论模型的准确性。将美国Wyatt公司生产DAWN HELEOSⅡ18角度散射测量仪、美国SEQUOIA公司生产的LISST-100xB粒径仪和美国Hobilabs公司的后向散射仪HydroScat-6Sprctral Backscattering Sensor(HS6)联动观测,构成后向散射系数光谱测量系统,分别测量不同水样的散射强度电压值、粒径分布及粒径浓度、后向散射系数等参数,提出了利用Mie散射理论计算未知折射系数物质的体散射函数β(λ,θ)的新思路及分离后向散射系数光谱的算法。选择已知折射系数m的石英砂作为颗粒物与采自不同油田区域的油污水进行配比,获取不同特性水样,测定相关数据。首先,根据Mie散射理论计算出各样本对应的水体体积散射函数β(λ,θ);其次,建立的DAWN HELEOSⅡ18角度激光散射仪测定散射强度对应的电压值V(θ)转化为体积散射函数β(λ,θ)的关系式;再次,根据最优化方法估算出油砂混合的等效折射系数mos以及油的折射系数mo;最后,利用β(λ,θ)和估算的mos值及mo计算出各类样本的后向散射系数bb(λ),分别建立油污水bb,o(λ)和石英砂bb,s(λ)与油砂混合总bb,os(λ)的分离算法。分离算法的建立一方面提高了水体石油类污染后向散射理论模型的准确性,另外一方面拓展了米散射理论在海洋水色遥感中的应用。
