Ternary Cu-2.71Zr-2.27B (wt.%) alloys were fabricated using powder metallurgy, i.e.,
mechanical alloying followed by cold pressing and sintering. Influence of the mechanical
alloying parameters on microstructural and morphological changes of Cu-Zr-B powder mixture
was investigated using scanning electron microscopy and X-ray diffraction. Stereological
analysis was employed to determine changes in size and shape of copper particles during 40
hours of mechanical alloying. It was shown that with an increase in mechanical alloying time,
the size of copper powder decreases. Williamson-Hall analysis was used to calculate crystallite
sizes (D, nm), lattice parameter (nm), lattice strain (ε, %), and dislocation density (ρ, m-2). It was
shown that with increasing mechanical allo ying time, lattice parameter as well as lattice strain
both increases. Particles undergo high forces through ball-particle-ball and wall-particle-ball
collisions during mechanical alloying. These col...lisions induce accumulation of dislocations in
copper matrix and a decreasing in its crystallite size due to dominant plastic deformation
mechanisms. Dislocation densities reach its maximum value at around 30 hours of mechanical
alloying, after which they decrease owing to the recrystallization of copper matrix.
