High temperature deformation mechanisms of cemented carbides and cermets

The motivation of this work derives from the need of the cutting tool industry to improve its products in order to support harder and harder working conditions, namely increasing cutting speeds and working on stronger modern materials. The lifetime of the ...

Tensile properties of irradiated Cu single crystals and their temperature dependence

Zhongwen Yao

Single crystal copper was irradiated with 590 MeV protons to a dose of 0.01 dpa at room temperature. Irradiated and unirradiated tensile samples were deformed and relaxation tests were performed at temperatures between 77 and 293 K. The tests show a strong ...

Automatic Monitoring of the Riddes Bridges using Electronic Inclinometers

Olivier Burdet

The paper presents an innovative method of measurement of long-term deformations of bridges. The use of high precision electronic inclinometers permits an efficient and cost-effective automatic monitoring of bridge deformations. The system is easily applic ...

Non-isothermal fusion bonding of polypropylene

Pierre-Etienne Bourban, John Christopher Plummer

The fusion bonding of neat polypropylene (PP) has been investigated under non-isothermal conditions with different initial adherend temperatures, and the results compared with results from bonds prepared under isothermal conditions with identical adherend ...

Laser annealing of shape memory alloys : A versatile tool for developing smart micro-devices

Yves Bellouard, Reymond Clavel, Thomas Lehnert, Thomas Sidler

From a shape change point of view, the shape memory effect is not intrinsically reversible. Therefore developing Shape Memory Alloys (SMA) actuators, i.e. devices producing a motion, requires a suitable method to bypass this intrinsic property. Since the s ...

Approche expérimentale du comportement mécanique des polymères en sollicitation rapide

In the more recent applications of technical polymers, they are frequently submitted to high strain rates. Being viscoelastic by nature, their mechanical properties are rate dependent. It is therefore important to investigate their properties over a wide r ...

A Framework for The Blackboard Model

The blackboard model is a flexible problem-solving approach where the data and knowledge rules are strictly separated. The data generated during a problem resolution, from a problem statement to a solution through various stages of inferences, is centrally ...

Two-Dimensional 29Xe Exchange NMR Measurements of Xenon Dynamics in Na-A Zeolite

David Lyndon Emsley, Bradley Floyd Chmelka

Two-dimensional (2D) exchange NMR is a powerful tool for measuring the dynamics and energetics of adsorbed xenon atoms undergoing slow exchange between the alpha-cages of Na-A zeolite. In this proceedings, we present recently published results, as well as ...
