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

Nadine Baluc

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 ...

Influence of microstructural heterogeneity on the scaling between flow stress and relative density in microcellular Al-4.5 %Cu

Andreas Mortensen, Yves Conde

We explore the influence of the metal microstructure on the compressive flow stress of replicated microcellular 400-mu m pore size Al-4.5 wt%Cu solidified at two different solidification cooling rates, in the as-cast and T6 conditions. It is found that the ...

In situ copper–alumina composites

Andreas Mortensen, Carmen Krüger

We present a process for the production of Cu-Al matrix composites containing between 25 and 30 vol.% in situ Al2O3. The composites are prepared by pressing, heat-treating and hot working blended powders of Cu, Al and CuO packed into copper alloy cans. The ...

Microstructure and mechanical properties of a W-2wt.%Y2O3 composite produced by sintering and hot forging

Nadine Baluc, Philippe Spätig, Robin Schäublin

A W-2Y(2)O(3) composite has been developed by powder metallurgy methods in collaboration with the Plansee Company (Austria). The microstructure of the composite was analyzed using transmission electron microscopy and electron backscatter diffraction in sca ...

Effect of ion-irradiation on the microstructure and microhardness of the W-2Y(2)O(3) composite materials fabricated by sintering and hot forging

Nadine Baluc, Philippe Spätig

A W-2Y(2)O(3) material was developed in collaboration with the Plansee Company (Austria). An ingot of the material having approximate dimension of 95 mm x 20 mm was fabricated by mixing the elemental powders followed by pressing, sintering and hot forging. ...

W-2 wt.%Y2O3 composite: Microstructure and mechanical properties

Nadine Baluc, Philippe Spätig, Robin Schäublin

A W-2Y(2)O(3) composite is produced by powder metallurgy, including the pressing of the mixed elemental powders, their sintering and hot forging. The microstructure of the obtained composite is investigated using light microscopy, scanning electron microsc ...
