Structural Features of Cu–Ag Alloys Obtained via Mechanical Alloying with the Use of Cold and Cryogenic Severe Plastic Deformation

Abstract

The structural features of Cu–Ag alloys mechanically synthesized by means of severe plastic deformation at a room and cryogenic temperature are revealed using X-ray diffractometry and electron microscopy and via in situ measurement of structure-sensitive characteristics such as shear stress depending on the deformation level. The effect of cryogenic strain temperature consists in a special character of change in the structure and shear stress of the formed alloys, which, in turn, affects the composition of the solid solution and the kinetics of structural transformations, as well as the mechanical properties.
