An aluminide（AlFe and α-（FeAl）） surface layer containing lower-Al was formed on ferritic-martensitic steel P92 by means of surface mechanical attrition treatment（sMAT） combined with a duplex aluminization process at lower temperatures,i.e.a packed aluminization followed by a diffusion annealing treatment below its tempering *** tests indicated that the lower-Al surface layer formed on the sMAT sample is more resistant to cracking and has better adhesion to the substrate in comparison with the Al 5Fe 2 layer formed on the as-received sample after the duplex aluminization *** steam oxidation measurements showed that the oxidation resistance is increased significantly by the lower-Al surface layer due to the formation of a protective（Fe,Cr）Al 2O 4 *** rate constant of oxidation was estimated to decrease from-0.849 mg^2 cm^-4h^-1 of the as-received material to^0.011 mg^2 cm^-4 h^-1 of the AlFe layer at 700 ℃.

The exhumation mechanism of high-pressure(HP) and ultrahigh-pressure(UHP) eclogites formed by the subduction of oceanic crust(hereafter referred to as oceanic eclogites) is one of the primary uncertainties associated with the subduction *** phase relations and densities of eclogites with MORB compositions are modelled using thermodynamic calculations over a P-T range of 1-4 GPa and 400-800℃,respectively,in the NCKFMAsHTO(NaO-CaO-KO-FeO-MgO-AlO3-siO2-HO -TiO-FeO) *** modelling suggests that the mineral assemblages,mineral proportions and density of oceanic crust subducted along a cold P-T path are quite different from those of crust subducted along a warm P-T path,and that the density of oceanic eclogites is largely controlled by the stability of low-density hydrous minerals,such as lawsonite,chlorite,glaucophane and *** a cold subduction P-T path with a geotherm of～6℃km,lawsonite is always present at 1.1 to >4.0 GPa,and chlorite,glaucophane and talc can be stable at pressures of up to 2.3,2.6 and 3.6 GPa *** such a P-T path,the density of subducted oceanic crust is always lower than that of the surrounding mantle at depths shallower than 110-120 km(subduction P-T path with a geotherm of～10℃km,the P-T path is outside the stability field of lawsonite,and the hydrous minerals of chlorite,epidote and amphibole break down completely into dry dense minerals at relatively lower pressures of 1.5,1.85 and 1.9 GPa *** such a warm subduction P-T path,the subducted oceanic crust becomes denser than the surrounding mantle at depths >60 km(>1.8 GPa).Oceanic eclogites with high HO content,oxygen fugacity,bulk-rock X[= MgO/(MgO + FeO)],X= AlO/(AlO + MgO + FeO)]and low X[= CaO/ (CaO + MgO + FeO + NaO)]are likely suitable for exhumation,which is consistent with the bulkrock compositions of the natural oceanic eclogites on the Earth’s *** the basis of natural observations and our calculations

在很多纸品回收厂,进入纸品回收流程中的许多压感胶粘剂（PsA）制品,如地址标签、胶粘便条和自粘邮票,被认为是产生“粘胶物质”问题的根源。美国邮政总署迅速地对此作出反应,并成为环保型胶粘剂开发计划的先锋。这一计划始于1995年,那时艰苦的工业努力致使这一计划得以成功。PsA的主要生产商solutia,为了开发这种环保型PsA,与面纸生产商、防粘纸生产公司、应用商、纸品回收厂和测试实验室一起共同开发。很多早期可再制浆的胶粘剂都是水溶性的PsA, 它的同题是防潮性差、粘性不足、在水流中易聚集。具有不同回收特点的胶粘技术被探讨,并且显微镜分析法被应用来确定胶粘剂颗粒在整个回收过程中的状况。solutia开发了一种新型的水基丙烯酸PsA,具有极好的粘接性、防潮性和可回收性能,在筛选过程中很容易筛除。这种新型PsA在实验室、试验工厂和工厂使用中显示出极好的可回收性能,是目前美国有资格用于自粘邮票的胶粘剂。
