Krzepnięcie Metali i Stopów
1998 nr 36 111--120
PL Nieustanne dążenie do zmniejszenia masy konstrukcji powoduje wzrost wymagań stawianych materiałom konstrukcyjnym. Dotyczy to również tworzyw odlewniczych, zarówno z grupy stopów Fe jak i Al. Wśród tych ostatnich najpowszechniej stosowanymi są stopy Al-Si często zawierające dodatek Cu i Mg, które umo[...]

EN Aluminium alloys are one of the most important casting alloys. Among them, the Al-Si alloys comprise perhaps the most important group – about 80% of the aluminium casts are made of them. These materials are characterized by a very good technological properties, good corrosion resistance and tribolog[...]

EN The paper deals with influence of multiple remelting on AlSi9Cu3 alloy with higher iron content on chosen mechanical properties. Multiple remelting may in various ways influence mechanical, foundry properties, gas saturation, shrinkage cavity, fluidity etc. of alloy. Higher presence of iron in Al-Si[...]

EN The impact of casting conditions on microstructure a and mechanical properties was described, especially for cast products from AlSi9Cu3 alloy. Particular attention was paid to the parameters of dendritic structure: DAS 1 and DAS 2. Selected mechanical properties (by static tension test) of test cas[...]

EN Secondary or multiple remelted alloys are common materials used in foundries. For secondary (recycled) Al-Si-Cu alloys, the major problem is the increased iron presence. Iron is the most common impurity and with presence of other elements in alloy creates the intermetallic compounds, which may negat[...]

PL W pracy badano wpływ obróbki termicznej T6 połączonej z podwójnym przesycaniem na mikrostrukturę, twardość oraz odporność na korozję stopu A316 (Al-4,93Si-3,47Cu w % wag.) otrzymanego metodą odlewania. Obróbkę termiczną T6 przeprowadzono w następujący sposób: w pierwszej kolejności stop poddano prze[...]
EN Effects of T6 heat treatment with double solution treatment on microstructure, hardness and corrosion resistance of a cast A319 (Al-4.93wt%Si-3.47wt%Cu) alloy were investigated. The T6 heat treatment comprised of the first solution treatment at 500±5°C for 8 h, the second solution treatment in the t[...]

EN The research focused on the influence of the solution temperature on the structure of precipitation hardening multi-component hypoeutectic aluminium alloys. The AlSi8Cu3 and AlSi6Cu4 alloys were used in the study and were subjected to a thermal-derivative analysis. The chemical composition and cryst[...]
