Journal ArticleDOI
Ultrahigh hardness and biocompatibility of high-entropy alloy TiAlFeCoNi processed by high-pressure torsion
Parisa Edalati,Ricardo Floriano,Yongpeng Tang,Abbas Mohammadi,Karina Danielle Pereira,Augusto Ducati Luchessi,Kaveh Edalati +6 more
TL;DR: The TiAlFeCoNi alloy with the L21-BCC crystal structure exhibited 170-580% higher hardness and 260-1020% better cellular metabolic activity compared to titanium and Ti-6Al-7Nb biomaterials, suggesting the high potential of HEAs for future biomedical applications.
Journal ArticleDOI
Concurrent strengthening of ultrafine-grained age-hardenable Al-Mg alloy by means of high-pressure torsion and spinodal decomposition
Yongpeng Tang,Wataru Goto,Shoichi Hirosawa,Zenji Horita,Seungwon Lee,Kenji Matsuda,Daisuke Terada +6 more
TL;DR: In this paper, the age-hardening behavior and precipitate microstructures of severely deformed and then artificially-aged Al-13.4%Mg alloy has been investigated by Vickers hardness test, X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM) and atom probe tomography (APT).
Journal ArticleDOI
Severe Plastic Deformation under High Pressure: Upsizing Sample Dimensions
Journal ArticleDOI
Phase transformation and microstructure evolution in ultrahard carbon-doped AlTiFeCoNi high-entropy alloy by high-pressure torsion
TL;DR: In this article, an FCC carbide was introduced in a BCC-based AlTiFeCoNi alloy by the assistance of CALPHAD thermodynamic calculations, and the alloy was synthesized by arc melting and processed by severe plastic deformation via the high-pressure torsion (HPT) method to generate defects.
Journal ArticleDOI
Multi-pass high-pressure sliding (MP-HPS) for grain refinement and superplasticity in metallic round rods
Yongpeng Tang,Kosei Sumikawa,Yoichi Takizawa,Manabu Yumoto,Yoshiharu Otagiri,Zenji Horita,Zenji Horita +6 more
TL;DR: In this paper, the multi-pass high-pressure sliding (MP-HPS) process was applied for grain refinement of rods with an upsized dimension to achieve a homogeneous microstructure throughout the cross section of the rod.
