One of the major aims of the modern materials foundry industry is the achievement of advanced mechanical properties of metals, especially of light non-ferrous alloys such as aluminum. Usually an alloying process is applied to obtain the required properties of aluminum alloys. However, the presented work describes an alternative approach through the application of vibration treatment, modificati...

L. Bernat, Poznan University of Technology, Faculty of Mechanical Engineering and Management, Division of Foundry, Poznan, Poland The paper presents an influence of the Dendrite Arm Spacing (DAS) microstructure parameter on the intergranular corrosion of AlSi7Mg aluminum alloy. The samples were subjected to the corrosion process for: 2,5; 12; 24; 48 and 96 hours in NaCl + HCl + H2O solution. It...

Various studies are being conducted on alloying materials for mechanical engineering with various unique elements. In particular, have been to improve its properties by including elements such as lithium, zirconium, ytterbium, and erbium in the composition of aluminum alloy. The article examines change wear resistance ability alloys aluminum-silicon aluminum-copper systems germanium oxide based...

We examined a group of 105 workers from a primary aluminum plant for the presence of polycyclic aromatic hydrocarbon (PAH)-DNA adducts in their WBC and 1-hydroxypyrene in their urine. Workers were recruited from five job categories with different PAH exposure: the anode factory; the bake oven; and the electrolysis and the pot-relining departments. Unexposed workers from the foundry department s...

Nowdays, motorcycles become a primary need for people, especially in Indonesia. This has resulted the increasing number of motorcycle spare parts waste. The waste is form components such as wheels, tires, drums, canvas, gear, chains and pistons many others. Until now, community not used this waste, use raw material casting connecting rods. Connecting rod itself component made aluminum. In study...

An increased lung cancer risk has been described among foundry workers. Polycyclic aromatic hydrocarbons (PAHs) and silica are possible aetiological factors. This study describes a urinary PAH metabolite, 1-hydroxypyrene (hpU), as well as the degree of cytochrome P450IA2 activity/induction as reflected by the urinary caffeine ratio (IA2) in 45 foundry workers and 52 controls; IA2 was defined as...
