Monday, 1.12.2003 HS1, Institute of Physics Time: 16:00h	Incommensurate grain boundaries in metals. Dr. Frédéric Lançon A grain boundary is incommensurate when the ratio of the periodicities of the two grains along the interface is an irrational number. In particular, this implies that its structure is not periodic. I will present studies on mono-atomic metals including gold, aluminum and copper. Depending on the met ... More ...
