Elevated temperature aluminum alloys produced by water atomization

A new rapid solidification technology based on the use of modified water atomization followed by powder consolidation route has been developed recently and applied for manufacturing of a set of alloys for various applications. The paper analyses mechanical behavior in the range of 20-300 °C and microstructure of some elevated temperature Al-Fe-Ce base alloys produced by the above mentioned process in comparison with properties of similar alloys by other technologies. Mechanical properties were studied by tensile tests and Vickers hardness measurements. Microstructure and microchemistry of powders and powder metallurgy alloys were studied by electron microscopy, electron probe microanalysis and X-ray diffraction methods.
