Different from that of the streams in alluvial plain, the motion of bed load in mountain streams depends not only on the flow conditions, but on the availability of this type of material also. From the data gathered in the reach between Fengjie to Xiangxi, it appears that the supply of gravels in motion from the bed surface is limited and most of the material comes from upstream and the tributaries. The narrow gorges create considerable backwater effect upstream in flood season. Owing to these peculiarities...

Different from that of the streams in alluvial plain, the motion of bed load in mountain streams depends not only on the flow conditions, but on the availability of this type of material also. From the data gathered in the reach between Fengjie to Xiangxi, it appears that the supply of gravels in motion from the bed surface is limited and most of the material comes from upstream and the tributaries. The narrow gorges create considerable backwater effect upstream in flood season. Owing to these peculiarities the motion of gravel as bed load is discontinuous both in space and in time. When there is plenty of supply of gravel the motion of bed load follows the general trend as indicated by the Einstein bed-load function. For rivers with very large depth, the average velocity is not a good parameter in correlating with the bed load motion as compared with the tractive force at the bed surface.

A large number of transverse-cracks occurred in the weld metal of AISI 321 tube welded with HOCrl8Ni9Si2 welding wire and HJ260 welding flux after storing on the sea shore for several years. The cracks, fracture appearance and corrosion products have been studied by means of optical microscopes, SEM, EM and X-ray structural analysis. The cracks with obvious directionality and large depth-width ratio form initially at the surface of weld metal and appear to be highly branched. The fracture surface appears as quasi-cleavage steps, chevron, fan-shaped and river patterns, accompanied with characteristic secondary cracks, square corrosion pits and austenite skeleton dendrite. The corrosion products contain a large a-mount of Cl-, SO4= and O2. After detailed identification the failures have been proved as a result of stress corrosion cracking. The causes of its formation and the measures to avoid the failure have been proposed. It has been clearly suggested that stress corrosion cracking in this case relates to α phase dissolution. The relationship between the different fracture patterns and the initial columnar crystals, as well as the equiaxed grains has also been discussed.

采用AISI321钢、H0Cr18N9Si2焊丝,HJ260焊剂自动焊接的管件,于海滨存放数年后出现了大量焊缝横向裂纹。应用金相、扫描电镜、电子探针,X光与化学分析等方法对裂纹,裂纹断口及腐蚀产物进行了研究。该裂纹始于焊缝表面;有明显的宏观方向性;深宽比大;金相形态为有主干与分枝的树枝状。断口形貌呈类解理台阶、山形、扇形、河流等花样,还伴随有二次裂纹、方形蚀坑、奥氏体枝晶骨架等特征。腐蚀产物含有极高的Cl~-、SO_4~=、O_2。经多方论证、确定是SCC。分析了其产生的原因,提出了防止措施。明确提出了SCC与α相溶解有关。讨论了不同断口花样与原始柱状晶和等轴晶的关系。

In this paper, 0bservational method and results on micro domain Structure of magnetic films with perpendicular magnetization have been studied in SEM. The methodical procedure includes that preparing a good dry Bitter pattern on the films surface and then observing by second electron image(SEI)with high resolution. Because SEI possesses large depth of focus and high resolution, this technique can be applied to study micro domain structure and its change in magnetization process.
