| Annotation: | The present proposal responds to the ESA-AO2009 announcement of opportunity and the current ELIPS Research Plan, being dedicated to Materials Sciences. The alloys of interest are peritectic TiAl-based alloys that are excellent candidates for near net shape casting of light-weight structural components, like aero-engine blades. When solidifying these alloys, microstructure formation sensitively depends on the acceleration forces that commonly evolve during centrifugal casting. To advance knowledge in this emerging technology sector, the GRADECET team proposes to investigate the gravity dependence of microstructure formation and segregation in peritectic TiAl-based alloys: attention is directed to the columnar-to-equiaxed transition of the pro-peritectic, primary β(Ti) phase and to the texture evolution during the peritectic reaction/transformation. A series of experiments are planed to be performed in μg, 1g and hyper-g conditions, taking advantage of available instruments onboard sounding rockets and ESA’s large diameter centrifuge. The experiments will be supported by dedicated modelling on well selected scales, all converging into a multi-scale model of microstructure formation. A special work package was defined to measure self- and interdiffusion coefficients in the liquid phase of the selected alloys, as to provide sound data for modelling. Diffusion measurements will start onboard sounding rockets but will ideally continue onboard the ISS. The proposed research is judged ambitious but well targeted and in line with the team’s competence. |

| Annotation: | A new class of high temperature composites consisting of a continuous refractory metal framework (Nb, Mo, W) embedded in a silicide matrix will be developed. Continuous (percolating) porous skeletons of refractory metal (Nb, Mo, W) will be infiltrated with molten silicon or silicon based alloy using gas pressure infiltration (GPI). During GPI partial reactions between melt and refractory metal will take place, forming silicides predominantly in the vicinity of the surface of porous precursor, leaving less free silicon for formation of silicides inside the porous structure, thus making in situ FGMs with gradiently increasing metal content towards the core of composite. |

| Annotation: | Aluminium alloys are widely applied in transport and precision machine industry mainly due to their high specific strength and light-weight. In this project, a team composed of researchers from Slovak Academy of Science and National Chung Cheng University of Taiwan are cooperated to develop ultrafine-grained Al-Al2O3 composites; and investigate the critical parameters of processing route that could effect on the mechanical strength as well as tribological performance of Al powder compacts. The proposed study will conduct experimental testing and theoretical modelling to investigate ultrafine-grained Al-Al2O3 composites related to mechanical properties, high strain rate deformation and tribological performances. In this project, ultrafine-grained Al-Al2O3 composites with four different fine atomised Al powders will be consolidated to study the effect of characteristics on mechanical properties of compacts and their thermal stability. A micro-force impact tester with environmental thermal control system (up to 150°C) would be set up in this research for testing high rate force-displacement curves under different impact speed. A numerical method that coupled genetic algorithm with FEM would be used to reverse finding the constitutive model of Al compacts with strain rate and temperature effects. The constitutive model could couple into ABAQUS software to examine the energy absorbing performance of machine components such as aluminium steering wheel and CNC components. A lateral force measurement technique attached to a nanoindenter system has proven to be one of the best ways of evaluating the scratch resistance, in which scratching at different locations at constant load can be used to investigate Al-Al2O3 composites quality and homogeneity. The nanowear procedure consists of sequential constant load scratches over the same track, with a low load topography measurement performed between each scratch, in which can be used to determine the friction and lubrication of Al powder compacts. Moreover, the tribological performance including coefficient of friction, wear, surface temperature and surface hardened layer will be evaluated using a tribo-meter and energy dispersive X-Ray spectroscopy (EDXS). Test conditions will include a wide array of geometry configuration, loading and relative speed for the evaluation of industrial applications. In addition, the mechanical properties data are then input to a suitably trained artificial neural network (ANN) in order to inversely derive the corresponding critical parameters of processing route such that the mechanical properties of the Al compact can be extracted. Through this proposed research, the processing route that influence the mechanical properties, high rate deformations, and tribological performances will be thoroughly investigated so that a novel ultra-fine grained Al-Al2O3 composite can be proposed to utilize in many industrial applications. |

| Annotation: | The project focuses on the research of new materials that would be suitable as tool materials in the field of technologies that use ultrasound energy. The preparation of these materials will be done by using powder metallurgy methods. Moreover classic tool materials coated with composite and / or gradient materials based on micro and nano particles will be also investigated. From the point of view of the preparation of experimental material the problem with homogeneous mixing of micro and nano phases into the matrix and their homogeneous distribution in the matrix will be investigated. The selection of experimental material will be focused on materials and coatings with desired physical characteristics such as good transmission of ultrasonic energy, resistance to high cycle or gigacycle fatigue. It is supposed that particularly the materials based on aluminum, iron and titanium will be used. |

| Annotation: | The project is focused on basic research of composite materials based on aluminum and its alloys reinforced with ceramic particles. The composite containing 10 to 20 wt. % Al2O3 particles will be prepared by dissolving the master alloy with 50 wt. % Al2O3. The master alloys will be prepared through a gas pressure infiltration method. In the frame of the project an effect of the following parameters will be studied: infiltration pressure, temperature, time with regard to the quality of Al-Al2O3 interface as well as reactions at the interface in case of aluminium alloy. Subsequently, an effect of pressure infiltration parameters on the dissolution kinetics of the master alloy in the melt and distribution of Al2O3 particles within the final composite will be studied. Finally, the mechanical and physical properties of the composite will be characterized. |

| Annotation: | The aim of the project is to develop a system that enables continuous monitoring of fatigue-damage in critical spots of the construction in operation with the random nature of the loading. The result of a solution of the project should be a model, which enables, on the basis of measurement of the time course of deformation at a critical point of construction, in real time to calculate the characteristics needed for the assessment of the reliable operation of the structure from the material’s fatigue perspective (fatigue damage accumulation in probabilistic interpretation, change the probability of premature fatigue-failure occurrence when the non-standard load situation occurs, the current residual fatigue-life, the probability of survival of the desired service life, etc.). The scientific contribution lies in the introduction of the probability approaches to the calculation of the parameters necessary for the evaluation of fatigue reliability of structure. |
