| 1 | γ'variant-sensitive deformation behaviour of Inconel 718 superalloy显示文摘Strengthening in Inconel 718 superalloy is derived from dislocation interaction withγ'precipitates,which exist in disk-shaped three possible orientation variants with their{100}habit plane normal to each other.The interactions between dislocations andγ'precipitates vary according to theγ'orienta-tion variants,which makes the deformation behaviour complicated and difficult to reveal experimentally.In this work,γ'variant distributions of Inconel 718 samples were tailored by ageing heat treatment under either tensile or compressive stress.Theγ'variant-sensitive deformation behaviours were then studied by in situ tensile tests via neutron diffraction at room temperature.It is demonstrated that yield-ing first takes place in grains oriented with<110>parallel to the loading direction.An identical lattice strain response to applied stress of both theγmatrix and theγ'precipitates was observed during yield-ing,suggesting that dislocations shearing through theγ'precipitates is predominant at this stage.Vari-ations in yield strength for samples with differentγ'variant distributions were observed,which can be attributed to different strengthening that arises from interactions between dislocation and differentγ'variants. | R.Y.Zhang H.L.Qin Z.N.Bi Y.T.Tang J.Araújo de Oliveira T.L.Lee C.Panwisawas S.Y.Zhang J.Zhang J.Li H.B.Dong | 2022 | Journal of Materials Science & Technology2022，，31： | 1 |
| 2 | An Engineering Application Tool for Visual Assessment of the Equilibrium Beach显示文摘An engineering application tool for prediction of the static equilibrium bay(Beach Mod)is established to describe two bay shape formulas by use of the programming software 'MATLAB' with a graphic user interface(GUI).The tool is user-friendly for engineering students for the design of beach shapes.This tool was tested through application on three types of beaches in Taiwan and Australia.By implementing the concept of Headland Control,the Beach Mod program allows users to draw a structure and create an artificial headland.The results indicate that Beach Mod can efficiently forecast beach changes as well as MEPBAY,a competing software package,while boasting a better user interface. | T.L.LEE D.S.JENG B.R.CHEN | 2007 | China Ocean Engineering2007，21，4： | 1 |
| 3 | 南中国海新生代板块重建显示文摘1引言 南中国海是太平洋最西部的一个巨大边缘海,北以华南大陆边缘,西以越南、南以加里曼丹和东以马尼拉海沟为界。盆地的洋壳现在正在马尼拉海沟处向东俯冲。我们根据所取得的来自南中国海盆地及周围陆块的海磁资料、地质资料和古地磁资料,对南中国海地区提出一个区域性新生代板块重建模式。 在南中国海地区的许多古地理重建中,可提出的有Taylor和Hayes(1980,1983),Holloway(1982),Parker和Gealey(1985),Ru和Pigett(1986),Daly等(1987,1991)、Jolivet等(1989)及McCabe和Cole(1989)。然而重要的是把任何古地理重建置于全球背景中。虽然有一些关于整个东亚地区的构造模式,例如Tapponnier等(1982)的碰撞挤出模式或Dewey等(1989)和Rowley(1989)的模式,模式推测沿红河断裂有250km的右旋位移,但我们没有把我们的模式限于依附先前提出的任何模式。相反,我们运用所获得的来自整个东南亚地区的古地磁和野外地质资以及来自盆地的海洋地质资料,对南中国海地区的构造演化建立了一个模式。我们运用3维图示工作台推导了不同构造块体的旋转极,然后试用于我们的模式以确定模式本身的一致性。当模式与先前的解释相抵触时,我们对所选择解释的输入数据作评价。在本文中我们从汇编东南亚地区出版的地质史文献开始(重点? | T.L.Lee 辛文锋 | 1995 | 海洋地质译丛1995，，3： | 0 |
