Sažetak

Most of gaseous elements (H2, N2, O2) and compounds (H2O, SO2, CO2, CO, NO then Cn Hm, NH3, H2S, PH3) melt in metals (liquid or solidified). Solubility of gases in metals play very important role in production of castings. Dissolution of gases cause casting defects, have negative influence on quality of casting and decrease usability of castings in respect of reduction of their tensile strength, material fatigue and impact resistance which influences directly density of the casting itself. Hydrogen as the only gas capable to solve in significant quantities in aluminum melt is the main factor influencing gas porosity.
