Autor: Vickey Nandal, Sae Dieb, Dmitry S. Bulgarevich, Toshio Osada, Toshiyuki Koyama, Satoshi Minamoto, Masahiko Demura

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-13 (2023)

Abstract In this paper, a state-of-the-art Artificial Intelligence (AI) technique is used for a precipitation hardening of Ni-based alloy to predict more flexible non-isothermal aging (NIA) and to examine the possible routes for the enhancement in st

MIOpt: optimization framework for backward problems on the basis of the concept of materials integration

Autor: Satoshi Minamoto, Koyo Daimaru, Masahiko Demura

Publikováno v: Science and Technology of Advanced Materials: Methods, Vol 3, Iss 1 (2023)

In materials design, it is very difficult to accurately design forward problems owing to the variety of scales and phenomena to be considered and the increasing number of input and output variables. In addition, it is necessary to reduce the number o

Prediction of continuous cooling transformation diagram for weld heat affected zone by machine learning

Autor: Satoshi Minamoto, Susumu Tsukamoto, Tadashi Kasuya, Makoto Watanabe, Masahiko Demura

Publikováno v: Science and Technology of Advanced Materials: Methods, Vol 2, Iss 1, Pp 402-415 (2022)

The continuous cooling transformation (CCT) diagram of steels is very important in considering the phase transformation depending on the cooling rate of a material; however, it is difficult to obtain the diagram for each steel because of much experim

Melt Pool Shape Evaluation by Single-Track Experiments and Finite-Element Thermal Analysis: Balling and Lack of Fusion Criteria for Generating Process Window of Inconel738LC

Autor: Jun Katagiri, Masahiro Kusano, Satoshi Minamoto, Houichi Kitano, Koyo Daimaru, Masakazu Tsujii, Makoto Watanabe

Publikováno v: Materials, Vol 16, Iss 4, p 1729 (2023)

Defects occur in laser powder bed fusion (L-PBF) such as the keyholing, lack of fusion, and the balling depending on the laser power (P) and the scan speed (V). The figure shows that the occupied regions of each defect are the process window and are

Thermal boundary resistance at Si/Ge interfaces by molecular dynamics simulation

Autor: Tianzhuo Zhan, Satoshi Minamoto, Yibin Xu, Yoshihisa Tanaka, Yutaka Kagawa

Publikováno v: AIP Advances, Vol 5, Iss 4, Pp 047102-047102-9 (2015)

In this study, we investigated the temperature dependence and size effect of the thermal boundary resistance at Si/Ge interfaces by non-equilibrium molecular dynamics (MD) simulations using the direct method with the Stillinger-Weber potential. The s
