WebbThe mechanism whereby grain boundaries are delineated and striations formed on polished surfaces of heated metal specimens has been examined. Experiments on electrolytically polished silver show that grooves form at grain boundaries at temperatures as low as 300° C and striations at 500° C in air.
WebbA theory is presented which describes the development of surface grooves at the grain boundaries of a heated polycrystal. The mechanisms of evaporation‐condensation and surface diffusion are discussed with the use of the Gibbs‐Thompson formula and the assumption that the properties of an interface do not depend on its orientation. r/d and dWebb13 apr. 2024 · We have developed a new cryogenic ring shear device at the University of Wisconsin–Madison to simulate cryosphere processes, with an emphasis on the physics of glacier slip.
