M. Szucki, D. Kalisz, J. Lelito, P. L. Żak, J. S. Suchy, K. W. Krajewski, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland The presented work focuses on solid particle interactions with the moving crystallization front during a solidification of the metal matrix composite. The current analyses were made for silicon carbide particles and ZnAl alloy with di...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mech...

In electron momentum spectroscopy (EMS), an incoming energetic electron (50 keV in this work) ionizes the target and the scattered and ejected electrons are detected in coincidence (at energies near 25 keV). From the energy and momentum of the detected particles, the energy omega and momentum q transferred to the target can be inferred. The observed intensity distribution I(omega, q) is proport...

Study of the corrosion behaviour of a magnetron sputtered Al–Cu/Al–Cu–Mg model alloy couple in sulphate solutions has been undertaken to gain insight into the galvanic coupling between the matrix and SAl2CuMg particles in the 2024 aluminium alloy (AA2024). Polarisation curves and local electrochemical impedance spectroscopy measurements (LEIS) were performed on the individual alloys and on the ...

Rice Husk Ash (RHA) of three different particle size ranges (50 – 75 μm), (75 – 100μm) and (100 – 150μm) in 3, 6, 9 and 12 % by weight was reinforced with the aluminium alloy using stir cast route. The microstructure and mechanical properties of the fabricated composites were analyzed. The results reveal that the tensile strength, compressive strength and hardness of the aluminum alloy composit...

Iliac bone aluminium was determined by neutron activation analysis in 34 patients with chronic renal failure and in eight control subjects. In 17 patients treated by haemodialysis there was a significant increase in the amount of aluminium (mean +/- SE = 152 +/- 30 ppm bone ash). In eight patients treated by haemodialysis and subsequent renal transplantation, bone aluminium was still significan...

Aluminium Phosphide poisoning and glucose‐6‐phosphate dehydrogenase deficiency are two commonly seen clinical presentations in Iran. However, hemolysis associated with Aluminium Phosphide poisoning is very rare. We report a case of concurrent Aluminium Phosphide poisoning and glucose‐6‐phosphate dehydrogenase deficiency in a 24 year old man presenting with intravascular hemolysis. Key words...

Abstract Aluminium LM13 alloy based hybrid particulate composites have been processed by adding boron carbide (B 4 C) and titanium diboride (TiB 2 ) particles. The wt% of is varied as 0, 3, 6, 9, 12, 15 a constant 3 used to prepare the composites. Stir cast route fabricate microstructures castings are examined using computer aided image analyzer. Vicker hardness, yield strength, ultimate tensil...
