Refinement Mechanism of Ultrafine-Grained CP-Ti Fabricated via Equal-Channel Angular Pressing

Metals, Journal Year: 2025, Volume and Issue: 15(2), P. 201 - 201

Published: Feb. 14, 2025

Grains of commercially pure titanium (CP-Ti) can be refined via rotary-die equal-channel angular pressing (RD-ECAP) to meet higher application requirements. However, the grain refinement mechanism CP-Ti during RD-ECAP has not been fully studied. Herein, was processed up four passes by obtain an ultrafine-grained structure. The microstructure evolution, mechanism, and dynamic recrystallization (DRX) behavior investigated TEM EBSD analysis. results revealed that after two passes, banded structures with numerous LAGBs inside were detected, while most grains equiaxed HAGBs average size about 0.5 μm. fraction reached 78.6% for four-pass sample, which than two-pass sample. deformed declined proportion recrystallized increased as pass number from four. misorientation gradient analysis showed subgrains evolved into new gradually generate ultrafine grains. concluded continuous DRX (CDRX). In addition, relationship between type processing conditions well stacking fault energies (SFEs) metals innovatively explored, providing a approach predicting microstructure.

Solving Ambiguity in EBSD Indexing of Long-Period Stacking Ordered (LPSO) Phase in Mg with Template Matching Approach

Crystals, Journal Year: 2024, Volume and Issue: 14(11), P. 932 - 932

Published: Oct. 28, 2024

Magnesium (Mg) alloys with long-period stacking ordered (LPSO) phases are receiving increasing interest because of their excellent mechanical performance. The close similarity in atomic sequences between different LPSO polytypes and Mg lattice often leads to ambiguous indexing electron backscatter diffraction (EBSD), a commonly used material characterization technique. Instead the Hough transformation approach commercial software, an alternative approach, which can catch subtle differences by matching experimental patterns simulated ones, is explored this study. Our results, showing ~94% mapping data being correctly indexed as target phase, 14H LPSO, demonstrate capability not only resolving but also distinguishing polytypes. This offers valuable, if unique, solution for microscale phases, enabling precise microstructure tuning further promote properties alloys.
