Body text
In-situ material tests using a synchrotron X-ray CT are new methods to observe fracture behavior of microstructures in materials. The methods are useful to take 3-D sequential images of such fracture behavior. At the beamlines BL47XU and BL20B2, the high-resolution CT system is available to perform 3D high-resolution imaging and sequential observations using an in-situ test rig.
Figure illustrates how an analysis model was created from part of the whole tomographic volume. The polygonal model in the Fig.(c) was extracted from the external form of the cell wall in the aluminum foam in Fig.(a) by a trilinear interpolation. Also the polygonal models of the micropores in Fig.(d) were similarly extracted from the volume in Fig.(b). The methods demonstrated in this study can apply the damage of various materials as well as metals and damage mechanism such as destruction with considerable accuracy can be specified.
