SEVERE PLASTIC DEFORMATION IN HIGHLY IMMISCIBLE

[19]. This observation contrasts strongly with those for CuAg and CuFe, and it thus indies that atomic motion during severe plastic deformation is not completely ballistic in such alloy systems. Other examples of incomplete mixing behavior in metals have been reported for FeAg [20], CuNb and CuMo [7,8] and CuTa [21].

NearPerfect Elastoplasticity in Pure Nanocrystalline

Apr 11, 2003 · Ductile metals and alloys undergo plastic yielding at room temperature, during which they exhibit workhardening and the generation of surface instabilities that lead to necking and failure. We show that pure nanocrystalline copper behaves differently, displaying nearperfect elastoplastic behavior characterized by Newtonian flow and the absence of both workhardening and neck formation.

Microstructure and Homogeneity of Nanocrystalline Co–Cu

Nanoscale energy dispersive xray spectroscopy (EDXS) shows that the Co concentration in both the interior of grains and the GB''s is close to the global composition, which proves that supersaturated solid solutions are indeed formed. In the meantime EDXS revealed that the mixing of Co and Cu in the solid solutions is homogeneous at nanometer scale.
