1Effect of Post Heat Treatment on Corrosion Resistance of Phytic Acid Conversion Coated Magnesium显示文摘An environment friendly chemical conversion coating for magnesium was obtained by using a phytic acid solution. The effect of post-coating 1heat treatment on the microstructures and corrosion properties of phytic acid conversion coated magnesium was investigated. It was observed that the microstructure and corrosion resistive properties were improved for the heat treated samples. The corrosion current density for bare magnesium, phytic acid conversion coated magnesium, and post-coating heat treated magnesium was calculated to be 2.48×105 , 1.18×106 , and 9.27×107 A/cm2 , respectively. The lowest corrosion current density for the heat treated sample indicated its highest corrosion resistive effect for the magnesium. The maximum corrosion protective nature of the heat treated sample was further confirmed by the largest value of impedance in electrochemical impedance spectroscopy studies.R.K. Gupta K.

2COREX工艺燃料比的影响因素显示文摘作为一种新型非高炉炼铁工艺,COREX工艺使用80%~85%非焦煤和15%~20%焦炭作为燃料,以满足对热量和还原剂的需求,并保证熔融气化炉内半焦床具有足够透气性。用于COREX工艺的非焦煤应满足一定的物化和高温性能,以稳定操作和提高产量。印度金达尔(JSW)钢铁厂拥有两座各年产80万t的COREX熔融还原炉,使用过几个煤种,发现不同煤种对操作会产生重要影响。统计分析表明,影响燃料比的主要因素包括煤的水分和挥发分、渣比和熔化速率。研究发现,生产率较高时,半焦床的稳定性和透气性就显得非常关键,因此反应后的半焦应具有较高的强度。P.

4Magnetotelluric investigation of lithospheric electrical structure beneath the Dharwar Craton in south India:Evidence for mantle suture and plume-continental interaction显示文摘Broad-band and long period magnetotelluric measurements made at 63 locations along -500 km long Chikmagalur-Kavali profile,that cut across the Dharwar craton (DC) and Eastern Ghat Mobile Belt (EGMB) in south India,is modelled to examine the lithosphere architecture of the cratonic domain and define tectonic boundaries.The 2-D resistivity model shows moderately conductive features that intersperse a highly resistive background of crystalline rocks and spatially connect to the exposed schist belts or granitic intrusions in the DC.These features are therefore interpreted as images of fossil pathways of the volcanic emplacements associated with the greenstone belt and granite suite formation exposed in the region.A near vertical conductive feature in the upper mantle under the Chitradurga Shear Zone represents the Archean suture between the western and eastern blocks of DC.Although thick (-200 km) cratonic (highly resistive) lithosphere is preserved,significant part of the cratonic lithosphere below the western DC is modified due to plume-continental lithosphere interactions during the CretaceouseTertiary period.A west-verging moderately conductive feature imaged beneath EGMB lithosphere is interpreted as the remnant of the Proterozoic collision process between the Indian land mass and East Antarctica.Thin (-120 km) lithosphere is seen below the EGMB,which form the exterior margin of the India shield subsequent to its separation from East Antarctica through rifting and opening of the Indian Ocean in the Cretaceous.D.
