Temperature measurement inside and near the weld pool during laser welding

LHOSPITALIER, Sylvie; BOURGES, Philippe; BERT, Alexandre; QUESADA, Jean; LAMBERTIN, Michel (Laser Institute of America, 1999)

The work in this article deals with the measurement of temperature fields inside and near the weld pool during laser welding. The laser source used for this study is a 7.5 kW CO2 laser, and the welded material is a UNS ...
Impact des contraintes résiduelles sur la déformation en usinage de plaques en 316L

CHERIF, Iheb; COTTON, Dominique; OUTEIRO, José; POULACHON, Gérard (2018)

La fabrication des plaques en 316L de grandes tailles et de faibles épaisseurs destinées aux échangeurs thermiques passe par plusieurs étapes de fabrication (laminage, traitement thermique et finalement l’usinage), afin ...
Influence of toolpath and clamping strategies on stainless steel plates distorsion after machining

CHARRONDIERE, Guillaume; CHERIF, Iheb; POULACHON, Gérard; COTTON, Dominique; OUTEIRO, José (2018)

Heat exchangers in nuclear power generation plants are made of thin stainless-steel plates assembled together in order to improve their efficiency and compactness. To ensure the assembly, the global distortion of those ...
Understanding the diffusion wear mechanisms of WC-10%Co carbide tools during dry machining of titanium alloys

RAMIREZ, Christophe; IDHIL ISMAIL; GENDARME, Catherine; DEHMAS, Moukrane; AEBY-GAUTIER, Elisabeth; POULACHON, Gérard; ROSSI, Frédéric (Elsevier, 2017)

The diffusion wear between a WC-10%Co tool and a Ti54M titanium alloy was investigated by studying the reaction between both the materials using a diffusion couple and studying their behavior during a machining test. In ...
Effect of Forestry Management and Veneer Defects Identified by X-ray Analysis on Mechanical Properties of Laminated Veneer Lumber Beams Made of Beech

VIGUIER, Joffrey; MARCON, Bertrand; GIRARDON, Stéphane; DENAUD, Louis (NC State University, 2017)

This study proposes an innovative model based on local grain angle measurements to predict the modulus of elasticity of LVL made from beech. It includes a veneers sorting method industrially compatible thanks to its low ...
(TaC/Ta2C) bilayer formed on carburized and annealed tantalum; development of a numerical growth model

CARETTE, Laurent; JACQUET, Philippe; COTTON, Dominique; VIGNAL, Vincent; FAURE, Sébastien (Elsevier, 2019)

This paper describes a model developed to simulate the evolution of carbide layers (TaC/Ta2C) formed during carburizing and annealing treatments of tantalum. The model is based on a parabolic evolution of the layer thickness ...
Phenomenological study of chip flow/formation and unified cutting force modelling during Ti6Al4V alloy turning operations

CHÉRIF, Iheb; DORLIN, Théo; MARCON, Bertrand; FROMENTIN, Guillaume; KARAOUNI, Habib (Elsevier, 2018)

Mechanistic approach for prediction of cutting forces are showing limits when it comes to enhance the cutting force modelling for specific applications of high-value added and thin parts, which are made of difficult-to-cut ...
