| 1 | 3D characterization of crystallographic orientation in polycrystals via EBSD显示文摘Electron Backscatter Diffraction(EBSD) has been used in conjunction with a Scanning Electron Microscope(SEM) combined with a focused ion beam(FIB) instrument to obtain three dimensional(3D) high resolution characterizations of crystalline microstructures.This work reports on continued development that has proceeded on this technique.The technique is based on automated in-situ serial sectioning using the FIB and characterization of the sections using automated EBSD or orientation imaging microscopy(OIM).The technique extends the powerful features of two dimensional OIM into the third spatial dimension.This allows additional descriptive microstructural parameters to be obtained,for example the morphology and the crystallographic indices of interface planes.This paper provides an overview of the technique and shows results from two different samples: pearlite colonies in a high carbon steel and twin related grain triplets in a NiCo thin film. | Stefan ZAEFFERER Stuart I.WRIGHT | 2007 | 中国体视学与图像分析2007，12，4： | 3 |
| 2 | Influence of sample preparation on nanoindentation results of twinninginduced plasticity steel显示文摘Nanoindentation is an attractive characterization technique,as it not only measures the local properties of a material but also facilitates understanding of deformation mechanisms at submicron scales.However,because of the complex stress-strain field and the small scale of the deformation under the nanoindenter,the results can be easily influenced by artifacts induced during sample preparation.In this work,a systematic study was conducted to better understand the influence of sample preparation methods on the nanoindentation results of ductile metals.All experiments were conducted on a steel(Fe-22Mn-0.65C,wt%)with twinning-induced plasticity(TWIP),which was selected for its large grain size and sensitivity to different surface preparation methods.By grouping the results obtained from each nanoindent,chemical polishing was found to be the best sample preparation method with respect to the resulting mechanical properties of the material.In contrast,the presence of a deformation layer left by mechanical polishing and surface damage induced by focused ion beam(FIB)scanning were confirmed by the dislocation-nucleation-induced pop-in events of nanoindentation. | Jiali Zhang Stefan Zaefferer | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，5： | 2 |

| 11 | Hydrogen effect on the mechanical behaviour and microstructural features of a Fe-Mn-C twinning induced plasticity steel显示文摘The influences of hydrogen on the mechanical properties and the fracture behaviour of Fe-22Mn-0.6C twinning induced plasticity steel have been investigated by slow strain rate tests and fractographic analysis.The steel showed high susceptibility to hydrogen embrittlement,which led to 62.9%and 74.2%reduction in engineering strain with 3.1 and 14.4 ppm diffusive hydrogen,respectively.The fracture surfaces revealed a transition from ductile to brittle dominated fracture modes with the rising hydrogen contents.The underlying deformation and fracture mechanisms were further exploited by examining the hydrogen effects on the dislocation substructure,stacking fault probability,and twinning behaviour in pre-strained slow strain rate test specimens and notched tensile specimens using coupled electron channelling contrast imaging and electron backscatter diffraction techniques.The results reveal that the addition of hydrogen promotes planar dislocation structures,earlier nucleation of stacking faults,and deformation twinning within those grains which have tensile axis orientations close to<111>//rolling direction and<112>//rolling direction.The developed twin lamellae result in strain localization and micro-voids at grain boundaries and eventually lead to grain boundary decohesion. | Xiaofei Guo Stefan Zaefferer Fady Archie Wolfgang Bleck | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，5： | 1 |
