Energy of Grain Boundaries of Different Type in fcc Solid Solutions, Ordered Alloys and Intermetallics with L12 Superstructure

O.B.Perevalova , E.V.Konovalova , N.A.Koneva , E.V.Kozlov

材料科学技术(英文)

The study of the triple junctions of the grain boundaries in some fcc solid solutions, ordered alloys and intermetallics with L12 has been carried out using the optical metallography and TEM methods. Two-types of the triple junctions were found in the alloys investigated (1), consisting of the bound...
