Figure 3
Copper jacket deformation during high pressure and temperature runs. Panels (a), (b) and (c) are 2D slices acquired at the I12 JEEP beamline of Diamond Light Source during a basalt carbonation experiment at confining pressures of 0.1, 1 and 20 MPa, respectively. Panels (d) and (e) are 3D renderings of the copper jacket surface during a gypsum dehydration and deformation experiment at the TOMCAT beamline of the Swiss Light Source. The axial shortening was 1.18 mm in (e) (6% of strain). Arrows (1) and (2) indicate the position of the sample/piston interfaces. Wrinkles and ridges (3) are due to the shortening of the sample under differential load during dehydration. (f) Photograph of the jacket after the experiments. |
