Microstructure of Gallstones

open access: yesGastroenterology, 1979
Electron microprobe analysis, x-ray diffraction, and infrared spectroscopy have been used to investigate the nature and arrangement of materials present in gallstones. Calcium phosphate and carbonate deposits present centrally in many stones were mixed with a pigmented phase containing copper and protein. In several stones, the central calcium deposits

Textures in Aluminum Forgings

open access: yesTexture, Stress, and Microstructure, Volume 14, Issue 1, Page 133-138, 1991., 1991
Texture and microstructure variations in a forged 7050 A1 alloy are analyzed. The results are compared to known texture effects in extrusion, shearing and plane strain deformation. Special attention is paid to locations where high local strains have been dctcted metallographically some of which show structural changes related to recrystallization and ...
