-layer by oxynitriding. Key words: magnesium alloys; titanium nitride; diffusive layers; hybrid method 1 Introduction Magnesium alloys are currently the most lightweight metallic construction... composite titanium nitride layers on magnesium alloys. In fact, one of the advantages of titanium is that it exhibits higher plasticity than chromium and thus it could potentially relax thermal stresses......
of alloys. For example, the lamellar microstructure in titanium alloys possess higher creep resistance, fracture toughness and crack propagation resistance, but the equiaxed microstructure has a good combination of strength and ductility [1]. The complex two-phase nature of titanium alloys not only provides a variety of microstructures ranging from the β-transformed (martensitic or lamellar......
]. In the past years, β heat treatment for titanium alloys has been extensively studied. Compared with traditional (α+β) heat treatment, β heat treatment offers a fully lamellar microstructure, which... attribute to two reasons. Firstly, there is a "critical point" [15] for the α colony size in various titanium alloys. When the α colony size is bigger than the critical α colony size, the elongation......

University of Technology摘 要:As multiple{11■2}twin variants are often formed during deformation in hexagonal close-packed (hcp)titanium, the twin-twin interaction structure has a profound influence on mechanical properties. In this paper, the twin-twin interaction structures of the{11■2}contraction twin in cold-rolled commercial purity titanium were studied......
