Significance for science
For the development of science are the most important findings in the field of impact types and morphology of foaming agents on uniformity of micro-and macro-structure of aluminum foams and stability of pores and pore size distribution. Quantitative microstructure characterization and comparison of different samples of aluminum foams are very difficult and complex task. Our research team has decided to use metodology in which quantitative microstructural characterization of aluminum foams is based on determining the distribution of pore size (DPS). Foam samples are produced by powder metallurgy process. As a foaming agent, we used five types TiH2 and dolomite powders with different particle size distribution. The average pore size and pore size distribution in the samples of aluminum foams were determined by image analysis of the microstructure made by light and scanning electron microscopy. Uniformity of the pore size distribution in the foam samples was studied as a function of the size distribution of the blowing agent, the average size of the powder AlSi12, concentration of foaming agent and foaming temperature and time. In general, the samples made by foaming with dolomite, had narrow pore size distribution and smaller average size of the pores. Narrow pore size distribution was observed in foam samples made from the finest dolomite powders with a narrow particle size distribution and mass concentration of the lowest (0.5 %) foaming agent. In contrast, in the aluminum foam samples made from rougher types of dolomite powder, with a wider distribution of particle size, the distribution of pore size with an increasing proportion of large-sized pores occurs. In addition, it has been shown that the degree of uniformity of microstructure foams depends largely on the temperature and foaming time, with the extension of time and temperature rise foam pore size distribution became broader. Experimental results and theoretical considerations on the development of microstructure of aluminum foams with closed cell porosity are summarized in the model, which requires the creation of conditions of homogeneous and uniform structure of foams.
Significance for the country
Results of the project contribute to the development of Slovenia. Certainly the maximal contribution is in the sense of technological or industrial development due to the possibility of new technological development such as development of new technologies, development of new products and increase of economics efficiency and competitiveness. Slovenian aluminium industry (IMPOL and TALUM) is traditionally positioned at the lower middle position of productive chain (primary aluminium, semi-products). Applied research projects run with the Slovenian academic sphere on selected programs with the aim to renovate and optimize the new products with higher added value on the bases of our own Slovenian knowledge. Aluminium foams and specially the products (profiles, panels with Al foam core) have high added value. Porous aluminium (Al foams) as a multipurpose material open the chance of breakthrough to niches with the highest added value (automotive industry, aircraft industry, machine engineering) as well as (in the case of foams with open porosity) in thermal technique (new generation of heat exchangers). With the referred interdisciplinary applied investigations the education of top most researchers is enabled through postgraduate education and collaboration with EU industry and research community.
