Effect of annealing temperature on the structure and properties of FeCoCrNiMo high-entropy alloy
FeCoCrNiMo high-entropy alloy was melted by vacuum arc melting. The alloys were vacuum annealed at 873, 1,073, and 1,273 K, respectively. X-ray diffractometer (XRD), scanning electron microscope (SEM), simultaneous thermal analyzer, microhardness tester,

CONTRACTILE PROPERTIES OF COMPRESSED MONOLAYERS OF ACTOMYOSIN [PDF]
1. Surface-spread actomyosin, compressed into fibers, shows biological properties of contractility and enzymic activity. 2. In unloaded contractions, wet and dry weight determinations show no appreciable water loss in contraction. The fibers also evince a strong ATP-ase activity. 3. A structural continuity in the fibers by

The Al Effects of Co-Free and V-Containing High-Entropy Alloys
In this study, five-component high-entropy alloys (HEAs) AlxCrFeNiV (where x denotes the molar ratio, x = 0, 0.1, 0.3, 0.5, 0.75, 1, and 1.5) were prepared using an arc-melting furnace. The effects of the addition of the Al on the crystal structures were

Mechanical Properties of Compressed Wood in Accordance with the Compression Ratio
本研究では圧縮木材を構造用接合具として使用することを意図し,様々な圧縮率のスギの圧縮木材を用いて,各種力学特性値の密度との関係を調べた。非圧縮材料の物性値を元にした基準化を行うことで,材質向上の傾向を明らかにするとともに,圧密の過程に伴う細胞の変形モデルと比較することで,定性的な説明を行った。結果,縦圧縮・引張および曲げ特性値は密度に比例したが,せん断特性はLR面とLT面でそれぞれ異なった。LT面横圧縮特性は弾性率,強度ともに密度上昇率に対し約2乗に比例して増大した一方,LR方向のそれは早材細胞が完全に圧密細胞に変わる圧縮率程度まではあまり変化無く,それ以降に急激に上昇する結果が得られた。これらの傾向をハニカムセルの変形を考慮する事でモデル化し,元材料の力学特性値と圧縮率 ...
