材料中成分和结构检测方案(扫描探针)

OXFORDINSTRUMENT SThe Business ofScience材料成分和结构 Metals alloys and ceramics have a place in almost all of globalmanufacturing. Whether it is the turbine blades in a jet engine， theceramic brake pads on a sports car or the steel cables for asuspension bridge， understanding the composition and structureof these materials is critical in understanding their properties.Using electron microscopy it is possible to characterise boththese properties. Understanding the distribution and compositionof nanoscale precipitates in Ni-based superalloys is crucial to understanding their performance under extreme temperatures. Using energy dispersive x-rayspectrometry (EDS) in the transmission electron microscope (TEM) allows -resolutionanalysis of these materials to determine the chemistry of these precipitates. Our X-MaxN100TLE EDS is the perfect solution for this； the sensitivity allows analysis to be performedquickly and accurately whilst remaining sensitive to trace elements that may arise fromcontamination during the manufacturing process. In the scanning electron microscope(SEM)， electronbackscatter diffraction canbe useddtto characterisestructural properties such as grain size and orientation aswell as stresses and strains within the . Our SymmetryEBSD is the perfect solution for any materials challenge，as the world’s first CMOS based EBSD camera it combinesspeed and sensitivity to acquire accurate results quickly. This speed and sensitivity are enabling -speed characterisation oflarge 3D volumes using slice and view techniques in the focusedion beam (FIB) ensuring that the structure and composition isunderstood not just in isiosloatliaotnion but inthe context of thesurrounding. For larger volumes still， x-ray computed tomography is the mostwidely used technique， these systems require -performance x-ray sources and detectors to ensure the highest quality data is collected. Our x-ray sources areused in tools to verify chemical composition of bulk materials by x-ray fluorence in primary and secondary (recycle) markets， as well as in x-ray diffractometers for precise crystallographicanalysis. X-ray imaging techniques of absorption or are the basis of measuring thicknessesand defects in composite and metal structures. @Oxford Instruments Metals alloys and ceramics have a place in almost all of global manufacturing.
