A delegation of the CINN is attending the Big Science Business Forum 2018. The conference takes place in Tivoli Congress Center in Copenhagen during 26-28 February, hosted by the Danish Ministry of Higher Education and Science and A 1000 delegates from more than 500 companies and organisations spanning approx. 30 countries have already registered.

The conference is arranged by the organisations CERN, EMBL, ESA, ESO, ESRF, ESS, European XFEL, F4E and ILL. A further nine Big Science organisations have joined the conference programme – ALBA, DESY, ELI-NP, ENEA, FAIR, MAX IV, SCK•CEN – MYRRHA, PSI and SKA – thereby gathering 18 of the world’s most advanced Big Science organisations under one roof.

Microstructural study of Co-based superalloys and ODS steels obtained by Spark Plasma Sintering (SPS)

Posted by / in Blog Industry, Featured News / No comments yet

The CINN has collaborated with IMDEA Materiales and the University Carlos III in the microstructural study of Co-based superalloys and ferritic ODS steels consolidated by Spark Plasma Sintering. The results of these studies were presented as oral presentations in the VI edition of the National Congress of Pulvimetallurgy that took place in Ciudad Real (Spain) from 7th to 9th June 2017.

The abstracts of the two lectures given are shown below:

Oxide Dispersion Strengthened (ODS) ferritic Steels are extraordinary candidates for nuclear applications due to their good behavior at high temperature and under irradiation conditions .ODS ferritic steel was produced by mechanical alloying and SPS to obtain a complex nanostructure. A four group elements (Y-Ti-Al-Zr) was selected to improve the stability of the precipitates since they are the main responsible for the thermal stability of fine structure. The heterogeneous distribution of stored energy due to the high energy attrition of MA powder will produce an inhomogeneous recrystallization during the consolidation step. After SPS consolidation a heterogeneous grain size distribution was attained, as recrystallization depends on the plastic deformation degree, on the composition of each particle and on the oxide dispersion promoted. Therefore sintering cycle was performed at 1373 K following fast heating rates (from 100 to 600 °C/min) to minimize porosity. The final microstructures were characterized by XRD and electron microscopy (SEM and TEM). In addition, Vickers microhardness and tensile tests was performed to analyze the mechanical response at R.T.

Co-based superalloys with ϒ-ϒ dual phase microstructure are considered a good alternative for high temperature in extreme environmental conditions applications due to their good strength, wear behavior and high oxidation resistance. In this work a fully prealloyed gas atomized powder with the nominal composition of Co-9Al-9W (at%) has been used. With the aim of promoting the ϒ´ phase precipitate, 2 at% of Ti and 2 at% of Ta have been added through mechanical alloying to the original powder. In order to reach a high level of densification maintaining an ultrafine grain size in the microstructure, the powder has been consolidated through Spark Plasma Sintering (SPS). The ϒ´ phase precipitate is obtained after subsequent heat treatments, first a solution treatment and then aging. By X ray diffraction (XRD) technique and scanning and transmission electron microscopy (SEM/TEM), the structural and microstructural changes produced after the heat treatments from the as obtained material have been monitored. The addition of Ti and Ta to the base alloy improves the ϒ’ phase precipitation process, and also affect to its thermal stability, improving the high temperature performance of the alloy. To characterize this influence on the ϒ´solution temperature, a thermo-gravimetric analysis has been performed for different compositions and heat treatments.

Mechanics, Resource and Diagnostics of Materials and Structures (MRDMS-2016)

Posted by / in Blog Industry, Featured News / No comments yet

The results of an international research on Zirconia-Graphene Nanocomposites was presented in the frame of the conference “Mechanics, Resource and Diagnostics of Materials and Structures (MRDMS-2016)” that took place in Ekaterinburg, Russia. The work was entitled “Black zirconia-graphene nanocomposite produced by spark plasma sintering” and was undertaken by scientists from the Moscow State University of Technology “STANKIN” and the CINN.

The research team success to fabricate theoretical dense electroconductive poreless black zirconia compacts by adding a small fraction of graphene oxide. This new functionality (electrical-thermal conductivity) enables the use of Spark Plasma Sintering (SPS) avoiding the limitations derived from the low thermal conductivity of zirconia and also allows the machining of complex-shaped components by electro-discharge machining methods (EDM).
