Temperature Effect on Solid Solution Formation Mechanism and Kinetics of Cu-Zn System under High Pressure Torsion

Abstract:

Influence of a nearly room and cryogenic severe deformation of a Cu-Zn powder mixture on a structural and phase transitions and kinetics of mechanical alloying was investigated. A sufficient retardation of structural and phase transformations and low homogeneity of solid solution made at 80K were established in comparison to processing at 273K. A lowering of solution formation kinetics rate is supposed to be due to lock of plastic deformation mechanisms, activated by thermal impact.
