- ItemVliv odplynění slitiny AlSi10Mg (EN AC 43000) na její vlastnosti při gravitačním odlévání do kovové formy(Technická Univerzita v Liberci, 2007-01-01) Dužda, David; Stuchlík, FrantišekThe topic of this thesis is determination of the influence of degasification on mechanical characteristics of alloy AlSi10Mg at gravity-die casting. The theoretical part deals with general summary of the most commonly used aluminium alloys in foundry industry and with the influence of other ingredients and foreign substances on the characteristics of the alloy and their codes in accordance with the Czech Standard ČSN EN 1706. Further are discussed the issues of gas content in alloys, methods of degasification and cases when gas saturation is carried out. In the practical part measurements of hardness, yield value, ultimate strength and elongation of four representative kinds of smelt were carried out. The thesis includes pictures of microstructure of each smelt sample.
