Severe Plastic Deformation (SPD) Processes for Metals
Akira Azushima,Reiner Kopp,Antti Korhonen,D.Y. Yang,Fabrizio Micari,G.D. Lahoti,Peter Groche,Jun Yanagimoto,Nobuhiro Tsuji,Andrzej Rosochowski,Akira Yanagida +10 more
TL;DR: In this paper, the authors defined severe plastic deformation (SPD) as metal forming processes in which a very large plastic strain is imposed on a bulk process in order to make an ultra-fine grained metal.
Journal ArticleDOI
Activation of TiFe for hydrogen storage by plastic deformation using groove rolling and high-pressure torsion: Similarities and differences
Kaveh Edalati,Kaveh Edalati,Junko Matsuda,Junko Matsuda,Akira Yanagida,Etsuo Akiba,Etsuo Akiba,Zenji Horita,Zenji Horita +8 more
TL;DR: In this article, the authors confirmed the significance of plastic deformation and formation of grain boundaries and cracks on activation for hydrogen storage, and showed that both annealing and high pressure torsion (HPT) were effective in hydrogenation.
Journal ArticleDOI
Formularization of softening fractions and related kinetics for static recrystallization using inverse analysis of double compression test
Akira Yanagida,Jun Yanagimoto +1 more
TL;DR: In this article, an inverse analysis for obtaining a flow curve equation, which accounts for inhomogeneous strain and temperature distributions, is applied to the evaluation of the softening fraction in a double compression test.
Journal ArticleDOI
Development of tribo-simulator for hot stamping
TL;DR: In this article, the authors used a hot flat strip drawing test machine for the purpose of confirming the coefficients of friction used for the FEM simulation of hot stamping, which can be used as values in the FTEM simulation.
Journal Article
Novel Approach to Determine Kinetics for Dynamic Recrystallization by Using Flow Curve
Akira Yanagida,Jun Yanagimoto +1 more
TL;DR: In this article, a new method to estimate the kinetics of dynamic recrystallization is proposed, which enables the estimation of the kinetic parameters directly from the flow curve of metal obtained by the hot compression test.
