Jan 30, 2019 · The numerous phase interface is the effective block to the movement of dislocation so as to improve the strength of alloy. Raabe et al. [ 23, 24 ] investigated Cu-8.2% Ag-4% Nb alloy and found that the increase of strength was due to the phase-barrier-type effect that arouse from lattice dislocation pile-ups at the interfaces. The microstructural evolution is followed in pure aluminium and nickel cold‐rolled over a large strain range. A number of dislocation configurations are characterized and classified and it is found that dislocation rotation boundaries are the dominant feature which subdivide the grains on a finer and finer scale as the strain is increased.

Glazov et al., MRS, Warrendale, PA 2001. I.R. Prigogine, Molecular Theory of Solutions, North Holland 1957. The fundamental idea for validating the microstructure evolution within CDD is sketched in figure 1.Consider an ensemble of dislocation loops with the same Burgers vector, occupying a domain of size figure 1a, where the slip system normal points in z direction. Each dislocation is located on a different slip plane and moves—driven by an external stress field—by glide only; no.
This paper summarizes and reviews the state‐of‐the‐art processing methods, structures and mechanical properties of the metal matrix composites reinforced with ceramic nanopa. It is known that interfaces, grain boundaries, phase boundaries, and surfaces play a crucial role in determining material strength and deformation mechanisms. Recent developments in mechanical testing and high-fidelity modelling techniques have made it possible to correlate interfacial phenomena with mechanical response.Scope.

Structures of the lamellar interfaces are characterized, and microchemistry and distribution habits of these elements along the γα 2 lamellar boundaries as well as the γ-γ lamellar and domain boundaries are analyzed. INTRODUCTION. Polysynthetically-twinned titanium aluminide PST-TiAl, a fully lamellar γ-TiAlα2- Ti3Al dual-phase alloy, is under evaluation for applications in rotary components in aircraft and automobile industries due to its high specific strength, and a high strength-retention capability at elevated-temperatures. However, the low ductility at room- to mid-high temperatures of the material hinders. MRS Online Proceedings Library Archive 5941999 INDEX TO VOLUME 16: 1998.

The above has reviewed the influence of cold deformation on precipitation behavior of Mg-Al, Mg-Zn, and Mg-RE alloy systems. Microalloying can influence microstructure evolution and precipitation behavior during deformation and heat treatment [1,16,17,68]. Thus, it is usually used to further improve the mechanical properties of existing Mg alloys.
