Serration and Reversion Treatment in Al-10mass%Zn Alloy [PDF]

open access: yes, 2004
The relationship between occurrence of serration and reversion heat treatment was studied by tensile test on Al-10mass%Zn alloy. Serration was observed for the furnace cooled specimen, but not for the as-quenched one and the shortly aged one, which ...

On Hirth Ring Couplings: Design Principles Including the Effect of Friction

open access: yesActuators, 2018
Rings with Hirth couplings are primarily used for the accurate positioning of axial-symmetric components in the machine tool industry and, generally, in mechanical components. It is also possible to use Hirth rings as connection tools.

Serration in A l-Zn Alloys Containing a Small Amount of Fe [PDF]

open access: yes, 2003
Effect of addition of Fe on the occurrence of serration in Al-12mass%Zn alloys was investigated. Specimens aged at 293K for various periods after quenching from various temperatures (T(Q)), 398K to 823K, were tensile-tested at room temperature. Serration

Effect of Heat Treatment on the Serration of Low-Concentrated Al-Zn Alloys [PDF]

open access: yes, 2002
The effect of heat-treatment conditions on occurrence of serration in Al-Zn alloys was investigated. Specimens were aged for various times up to 2.6Ms at 293K or 273K after quenching from various temperatures (T(Q)), 473K to 853K, and tensile-tested at ...

Aerodynamic Performance of Different Trailing-edge Serrations for High Reynolds Number Flows around Wing-flap System [PDF]

open access: yesJournal of Applied Fluid Mechanics
In the present work different trailing-edge serration models are designed and their aerodynamic performances at realistic landing conditions around a wing-flap system are investigated. The serration model with the best performance is then introduced. The

Ectopic Expression of BcCUC2 Involved in Sculpting the Leaf Margin Serration in Arabidopsis thaliana

open access: yes, 2023
Leaf margin serration is a morphological characteristic in plants. The CUC2 (CUP-SHAPED COTYLEDON 2) gene plays an important role in the outgrowth of leaf teeth and enhances leaf serration via suppression of growth in the sinus.
