布鲁克扫描电镜专用原位纳米力学测试系统PI 88

Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.

The evolution of texture and microstructure during plastic deformation controls the bulk mechanical properties of virtually all materials used to manufacture engineering components and equipment. SEM based in-situ tensile/ compression testing allows investigating the onset of plastic deformation as well as all intermediate deformation stages. Microstructure and texture evolution can be quantified when combining this technique with EBSD. The quantitative results can then be used for refining the plastic deformation theory as well as for confirming the existing simulation models.
