Improved mechanical properties of Co-free high-entropy Cantor alloy: A first-principles study

Autor: Ivan Lobzenko, Daixiu Wei, Mitsuhiro Itakura, Yoshinori Shiihara, Tomohito Tsuru

Publikováno v: Results in Materials, Vol 17, Iss , Pp 100364- (2023)

High-entropy alloys (HEAs) have received attention because of their excellent mechanical and thermodynamic properties. A recent study revealed that Co-free face-centered cubic HEAs could improve strength and ductility, which is crucial for nuclear ma

Atomic Stress State Inside fcc and bcc Random Alloys: A First-Principles Approach

Autor: Yoshinori Shiihara, Yuki Itai, Ivan Lobzenko, Tomohito Tsuru

Publikováno v: Frontiers in Materials, Vol 9 (2022)

The stress state at an atomic level and its governing physics inside a random alloy are essential elements in developing a model for solid solution strengthening in random alloys, which is one of the primary strengthening mechanisms of high-entropy a

First-principles atomic level stresses: application to a metallic glass under shear

Autor: Ivan Lobzenko, Tomohito Tsuru, Yoshinori Shiihara, Takuya Iwashita

Publikováno v: Materials Research Express, Vol 10, Iss 8, p 085201 (2023)

Unlike crystalline alloys, metallic glasses (MGs) do not possess distinctive defects but exhibit a highly heterogeneous response to shear deformation. The difficulties in describing such non-uniform behaviour hamper the prediction of the mechanical p

Finite element analysis on rolling contact fatigue of surface nanostructured steel (Effect of friction coefficient on mean shear stress under cyclic loading)

Autor: Yoshinori SHIIHARA, Yoshitaka UMENO, Nozomu ADACHI, Yoshikazu TODAKA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 86, Iss 882, Pp 19-00270-19-00270 (2020)

This study provides a theoretical investigation on shear stress distribution inside a steel roller with a nanostructured surface, manufactured by the severe plastic deformation and induction heating processes, under a rolling contact fatigue testing,

Fast quasi-implicit NOSB peridynamic simulation based on FIRE algorithm

Autor: Yoshinori SHIIHARA, Shoki TANAKA, Nobuhiro YOSHIKAWA

Publikováno v: Mechanical Engineering Journal, Vol 6, Iss 3, Pp 18-00363-18-00363 (2019)

The peridynamics is a particle methods considered superior to the finite element method in describing fracture phenomena since fracture can be simply expressed as bond breaking between the peridynamics particles. The Non-Ordinary State-Based (NOSB) p
