Influence of thermo-mechanical history on the ordering kinetics in 18 carat Au alloys

Nadine Baluc, Helena Van Swygenhoven, Steven Van Petegem, Marina Garcia Gonzalez

Precious alloys are subjected to a series of mechanical and thermal operations during manufacturing. For 18 carat gold alloys the processing operations can induce L1(0) ordered nanodomains, known to lead to the buildup of residual stresses, which are the p ...

Enhanced precipitate growth at reduced temperatures during chemical ordering in deformed red gold alloys

Nadine Baluc, Helena Van Swygenhoven, Steven Van Petegem, Marina Garcia Gonzalez, Samy Hocine

Manufacturing of red gold components relies widely on controlling the formation of ordered precipitates during thermo-mechanical processing. The ordered phase hardens the material, makes it less workable and introduces residual stresses. We show that an in ...

The accomplishments of lithium target and test facility validation activities in the IFMIF/EVEDA phase

Nadine Baluc

As part of the engineering validation and engineering design activities (EVEDA) phase for the international fusion materials irradiation facility IFMIF, major elements of a lithium target facility and the test facility were designed, prototyped and validat ...

Microstructure and tensile properties of ODS ferritic steels mechanically alloyed with Fe 2 Y

Nadine Baluc, Philippe Spätig

An oxide dispersion strengthened ODS ferritic steel has been produced by mechanical alloying of Fe–14Cr–2W–0.2Ti (wt.%) prealloyed powder with 0.55 (wt.%) Fe2Y intermetallic particles and consolidated by hot isostatic pressing. The microstructure after the ...

Investigation of microstructure and mechanical properties of W-Y and W-Y2O3 materials fabricated by powder metallurgy method

Nadine Baluc, Lyubomira Veleva

W-2Y, W-1Y(2)O(3) and W-2Y(2)O(3) materials have been fabricated using two different powder metallurgy methods. While W-2Y and W-1Y(2)O(3) have been fabricated using mechanical alloying and hot isostatic pressing (Hipping), W-2Y(2)O(3) has been fabricated ...

Microstructure examination of Fe-14Cr ODS ferritic steels produced through different processing routes

Nadine Baluc, Zbigniew Oksiuta

Various thermo-mechanical treatments were applied to refine and homogenise grain size and improve mechanical properties of hot-isostatically pressed (HIP) 14%Cr ODS ferritic steel. The grain size was reduced, improving mechanical properties, tensile streng ...

Investigation of microstructure and microhardness of pure W and W-2Y(2)O(3) materials before and after ion-irradiation

Nadine Baluc, Philippe Spätig

Pure W and W-2Y(2)O(3) materials were fabricated using powder metallurgy method. The microstructures of the materials were investigated by electron back-scattered diffraction and transmission electron microscopy techniques. Both materials contain 1-2 mu m ...

Effect of vanadium addition on the microstructure and mechanical properties of the ODS ferritic steels

Nadine Baluc, Zbigniew Oksiuta

In this work, the effects of vanadium addition in the range of 0.3-3% (in weight percent) for an oxide dispersion strengthened reduced activation ferritic (ODS RAF) steel were investigated. Samples of the V-modified steel have been prepared using elemental ...

Recent progress in R&D on tungsten alloys for divertor structural and plasma facing materials

Nadine Baluc, Ho Ling Li, Antoine Cyril David Hoffmann

Tungsten materials are candidates for plasma-facing components for the International Thermonuclear Experimental Reactor and the DEMOnstration power plant because of their superior thermophysical properties. Because these materials are not common structural ...

First-principles model for phase stability, radiation defects and elastic properties Of W-Ta and W-V alloys

Nadine Baluc

Tungsten alloys are candidate materials for DEMO divertor applications because of their high melting point and low sputtering yield. We explore, using ab initio methods, the phase stability trend of W-Ta and W-V alloys. The available experimental phase dia ...
