Electrical conductivity characterized at varying strains in spiral cut high-pressure torsion discs
Evander Ramos, Takahiro Masuda, Zenji Horita +1
High-pressure torsion (HPT) imparts inhomogeneous strain to process discs with low strain in the center and higher strain at the outer edge. Microscopy and microhardness indentatio…
Strain effects on the wear rate of severely deformed copper
Evander Ramos, Takahiro Masuda, Sina Shahrezaei +2
A variety of severe plastic deformation (SPD) techniques have been developed to process materials to high strains and impart microstructural refinement. High pressure torsion (HPT)…
Achieving highly strengthened Al-Cu-Mg alloy by grain refinement and grain boundary segregation
Takahiro Masuda, Xavier Sauvage, Shoichi Hirosawa +1
An age-hardenable Al-Cu-Mg alloy (A2024) was processed by high-pressure torsion (HPT) for producing an ultrafine-grained structure. The alloy was further aged for extra strengtheni…
