Residual stresses of friction melt bonded aluminum/steel joints determined by neutron diffraction

Near interfacial residual stresses are investigated in a joint composed of aluminum alloy and dual phase steel. A small step neutron diffraction scan was initially performed to determine the weld interface position along the measured transverse cross secti ...

Miniaturized tube fixed plug drawing: determination of the friction coefficients and drawing limit of 316 LVM stainless steel

Jean-Marie Drezet, Stefano Mischler, Nicolas Paul Henry Chobaut, Bastien De Marco, Vance Nguyen, Stéphane Dobler

Tube drawing with a ﬁxed plug is investigated experimentally and numerically in order to optimise an industrial pass sequence. Tube drawings are performed on a laboratory drawing bench equipped with force, displacement and temperature sensors. The drawing ...

Stress generation during the quenching of large AA2618 forgings: Finite element computations and validation against neutron diﬀraction measurements

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Denis Carron

Solutionising and quenching are key steps in the fabrication of heat treatable aluminium parts such as AA2618 compressor impellers for turbochargers. Quenching not only dictates the mechanical characteristics of the product but also induces residual stress ...

Measurements and Modeling of Stress in Precipitation-Hardened Aluminum Alloy AA2618 during Gleeble Interrupted Quenching and Constrained Cooling

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Denis Carron

Solutionizing and quenching are the key steps in the fabrication of heat-treatable aluminum parts such as AA2618 compressor impellers for turbochargers as they highly impact the mechanical characteristics of the product. In particular, quenching induces re ...

Characterisation of precipitation upon cooling of an AA2618 Al-Cu-Mg alloy

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Denis Carron

The precipitation of an AA2618 Al-Cu-Mg alloy is monitored during isothermal holdings and continuous coolings. The Time-Temperature-Property and Continuous-Cooling-Precipitation diagrams of AA2618 are obtained using in-situ resistivity and differential sca ...

Modeling of GP (I) zone formation during quench in an industrial AA7449 75mm thick plate

Jean-Marie Drezet, Charles-André Gandin, Patrick Schloth

The GP(I) zone formation during quench is simulated in an industrial Aluminumalloy AA7449 75mmthick plate by using a multi-class precipitation model. For this purpose, results of in situ SAXS experiments are reported. A methodology is presented that takes ...

Quench-Induced Stresses in AA2618 Forgings for Impellers: A Multiphysics and Multiscale Problem

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Gilles Michel, Denis Carron

In the fabrication of heat-treatable aluminum parts such as AA2618 compressor impellers for turbochargers, solutionizing and quenching are key steps to obtain the required mechanical characteristics. Fast quenching is necessary to avoid coarse precipitatio ...

Measurement of Mechanical Coherency Temperature and Solid Volume Fraction in Al-Zn Alloys Using In Situ X-ray Diffraction During Casting

Jean-Marie Drezet, Güven Kurtuldu, Bastien Gilbert Pierre Mireux

During solidification of metallic alloys, coalescence leads to the formation of solid bridges between grains or grain clusters when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behavior ...
