Temperature Dependence of Facet Ridges in Crystal Surfaces
, 1998 The equilibrium crystal shape of a body-centered solid-on-solid (BCSOS) model on a honeycomb lattice is studied numerically. We focus on the facet ridge endpoints (FRE).

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6
Advanced Engineering Materials, EarlyView.The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

Investigation of the mechanism of the indentation size effect for titanium
Mechanical Engineering Journal, 2019 In this study, we investigated the mechanism of the indentation size effect for Ti, whose crystal structure is hexagonal close-packed. Indentation tests were performed for two types of single-crystal Ti with different crystal orientations: (0001) and ...

Elastic Deformation of Polycrystals
, 2002 We propose a framework to model elastic properties of polycrystals by coupling crystal orientational degrees of freedom with elastic strains. Our model encodes crystal symmetries and takes into account explicitly the strain compatibility induced long ...

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Orientation and Crystallization in Polyester (II)
Kobunshi Kagaku, 1960 ポリエチレンオキシベンゾエートからつくった無定形無配向の未延伸繊維の連続延伸について研究した。繊維の延伸が二つの過程, すなわち, 分子鎖の弾性的な伸長配列と流動とから成り, 延伸後の繊維の複屈折率, 切断強伸度, ヤング率などが延伸時の張力ときわめて密接な関係を示すことを知った。限界張力 (0.1～0.2g/d) を境にして, 延伸張力と延伸繊維の性質との関係が急変することから, 限界張力以上では急激に結晶化がすすむと考え, 延伸機構を提案した。
