Paper Abstract

A new micro-tomography system for materials science has been developed at BL20B2 in SPring-8. The system enables us to do stretching, press and twist of materials with a translation stage and two precise rotation stages arranged opposite to each other. Each deformation can be operated with constant moving rate. The maximum load is about 2 kN because of the hardness of the precision stages. The X-ray image detector consists of visible light conversion system and sCMOS camera. The effective pixel size is variable by changing a tandem lens between 2.7 μm/pixel to 13.2 μm /pixel discretely. As a demonstration of the system, a viscoelastic object was imaged. The experimental conditions are follows, X-ray energy: 25 keV, exposure time: 5 msec, number of projections: 900, single scan time: 7.5 sec, pixel size: 13.2 μm /pixel and field of view: 27.0 mm x 3.9 mm. The stretching rate was 1 μm /sec to 5 μm /sec. A metastable state such as tensile loading of viscoelastic materials is possible with this system.
