1Passivity breakdown on 436 ferritic stainless steel in solutions containing chloride显示文摘Passivity breakdown on 436 ferritic stainless steel(FSS) has been investigated in solutions containing different concentrations of chloride at 25?C and interpreted in terms of the point defect model(PDM). The measured near-normal distributions of passivity breakdown potentials for 436 FSS under experimental conditions are in good agreement with the calculated results according to the PDM. The linear dependence of breakdown potential on the square root of potential scanning rate, which was described by the PDM,provides the estimation of the critical concentration of condensed vacancies at the metal/film interface,which leads to the passivity breakdown. This value is in good agreement with that calculated from the microstructure properties of the alloy substrate and the barrier layer of the passive film. This study demonstrates the validity of the PDM in describing the passivity breakdown on 436 FSS in NaCl solutions.Jiaming Wang Shengsheng Qian Yanhui Li Digby D.Macdonald Yiming Jiang Jin Li 2019Journal of Materials Science & Technology2019,35,4:2
2磁化率各向异性:在沉积学、火成岩石学以及构造地质学中的应用显示文摘一、引言如Graham(1954)所注意到的,磁化率各向异性(A MS)在研究地质过程中有很多用途。这种各向异性反映岩石磁化中磁化强度的方向性变化,主要是其中铁的氧化物特别是磁铁矿和赤铁矿。A MS常用一个椭球体表示,其三个主轴从大到小依次为k1、k2和k3William D.MacDonald Brooks B.Ellwood 张志强 1989世界地质1989,8,1:2
