WebJun 19, 2024 · Abstract and Figures. Precipitation from solid solutions and supersaturated solutions is a very important process as it plays an important role in the structure and properties of metals/alloys ... WebNov 7, 2024 · In this work the interaction of an edge dislocation with coherent and various non-coherent precipitates was studied. Based on the simulations and derived model the following conclusions are reached.
WebA coherent boundary is one for which atomic positions on either side of the boundary are correlated. This is illustrated for a coherent precipitate (yellow) in the top diagram. The lower diagram shows a similar precipitate, but with an incoherent boundary. Atoms in the matrix and the lattice are no longer in register across the interface. If ... WebCOHERENT PRECIPITATES: They are precipitates which have crystal structure and atomic arrangement that show a continuous relationship with the matrix from which they are formed. The matrix crystal …

In the present work, PALS was applied to the study of the precipitation process in aluminium alloy 6061. The objective of the present work was to investigate the role of WebThey are precipitates which have crystal structure and atomic arrangement that show a continuous relationship with the matrix from which they are formed. The matrix crystal structure is disrupted to a large extent and this highly impedes the motion of dislocations even if the dislocation just passes near the coherent precipitates.
