چکیده انگلیسی


• High quality ufg/nc Ti was prepared through mechanical milling and consolidation.
• High purity, very low porosity and high ductility were obtained.
• Grain size, strain rate and temperature effects were comprehensively investigated.
• The texture evolution of the ufg/nc samples under compression was determined.
• The viscoplastic KLF model was used to correlate the experimental results.

High quality bulk ultrafine-grained/nanocrystalline titanium samples were prepared through room temperature mechanical milling and conventional consolidation processes. The prepared bulk samples showed high purity, very low porosity and high ductility under compression. The dependency of yield stress and post-yielding behavior on grain size, strain rate and temperature were comprehensively studied. The texture evolution of the ufg/nc samples under compression was measured by synchrotron XRD. On the macroscopic scale, the viscoplastic phenomenological Khan–Liang–Farrokh (KLF) model was used to correlate the experimental results of the ufg/nc Ti.
