Different Nanocrystallization Sequence during High Pressure Torsion and Thermal Treatments of Amorphous Cu₆₀Zr₂₀Ti₂₀ Alloy

摘要

Nanocrystallization behavior of Cu₆₀Zr₂₀Ti₂₀ amorphous ribbon induced by severe plastic deformation and by linear heating thermal treatment has been compared. Thermal treatment of the as-quenched ribbon results in the joint formation of two crystalline phases, on contrary, plastic deformation at room temperature induces the precipitation of only Cu₂ZrTi.
