Description
- Die Erfindung betrifft eine kaltaushärtende Aluminiumgusslegierung, die auf Basis von Hüttenaluminium Al 99,9 erschmolzen wurde und bei hoher Zugfestigkeit und Streckgrenze noch eine Dehnung von deutlich über 1 % aufweist, sowie ein Verfahren zur Herstellung eines Aluminiumgussteils.
- Aus dem Werkstoff-Datenblatt ENAC-46200 ist als genormte Gusslegierung vom Typ G-AlSi8Cu3 die Legierung 226A (VDS Liste) bekannt. Die chemische Zusammensetzung dieser Legierung wird in Gewichtsprozent (Gw%) wie folgt angegeben: Silicium 7,5 - 9,5 Gw%, Eisen max 0,8 Gw%, Kupfer 2 - 3,5 Gw%, Mangan 0,15 - 0,65 Gw%, Magnesium 0,05 - 0,55 Gw%, Nickel max 0,35 Gw%, Zink max 1,2 Gw%, Titan max 0,25 Gw%, Blei max 0,25 Gw%, Chrom max 0,15 Gw%, Rest Aluminium sowie andere Beimengungen 0,05% (einzeln) und 0,25Gw% (insgesamt).
- Aus M. Schaefer und R.A Fournelle, "Effekt of strontium modification on near-threshold fatigue crack growth in an Al-Si-Cu die cast alloy", Metallurgical and Materials Transactions 27A, 05/1996, 1295-1301, sind Al-Si-Cu-Fe-Zn-Mn-Legierungen mit Zusatz von Sr bekannt.
- Ausgehend davon soll eine kaltaushärtende Aluminiumgusslegierung sowie ein Verfahren zur Herstellung eines Aluminiumgußteils mit hoher Zugfestigkeit und Streckgrenze bei gleichzeitig verbesserter Duktilität angegeben werden. Die Legierung soll gut vergießbar und zur Herstellung thermisch hoch beanspruchbarer Gussteile geeignet sein. Die Gussteile sollen auch mit herkömmlichen Mitteln gut schweißbar sein.
- Zur Lösung des ersten Teils dieser Aufgabe wird eine neue AlSi9Cu3 mit zusätzlichen Gehalten an Mangan, Zink, Strontium und Obergrenzen für Magnesium, Eisen und Titan gemäß kennzeichnendem Teil von Patentanspruch 1 angegeben. Das neue Verfahren ist durch die im Patentanspruch 2 definierten Maßnahmen gekennzeichnet.
- Im folgenden wird die Erfindung mit einer Standartlegierung verglichen. Dabei wurden die Werte von Zugfestigkeit, Dehngrenze und Dehnung an einem im Schwerkraftkokillenguss gegossenen Probestab gemessen, der auf folgende Abmessungen abgedreht wurde: Probendicke a= 3mm, Probenbreite b= 8mm, Kopfbreite B= 12mm, Kopfhöhe h= 15mm, Anfangslänge L0= 30mm, Versuchslänge Lc= 33mm und Gesamtlänge Lt= 80mm.
- Als Vergleichslegierung wird eine 226A-Gusslegierung mit folgender Zusammensetzung verwendet:
- Si 8%, Fe 0,6%, Cu 3,0%, Mn 0,3%, Ni 0,2%, Zn 1,0%, Ti 0,2%, Pb 0,1%, Sn 0,1%, Mg 0,45 andere Beimengungen: einzeln 0,05, insgesamt 0,25%, Rest Aluminium.
- Die Gusslegierung G-AlSi8Cu3 (Werkstoff Nr. 3.2162.05) weist im Gusszustand folgende Werkstoffeigenschaften auf:
- Streckgrenze Rp0,2 = 100 MPa
- Zugfestigkeit Rm = 170 MPa
- Dehnung A50mm = 1%
- Der Vergleich zwischen der Legierung 226A nach dem Stand der Technik und der erfindungsgemäßen Legierung zeigt die überlegenen Eigenschaften der erfindungsgemäßen Legierung, da die Werte für
Streckgrenze Rp0,2 ≥ 170MPa
Zugfestigkeit Rm ≥ 230 MPa bei gleichzeitig hoher
Dehnung A50mm > 1.5% gemessen wurden. - Außerdem wurden die Gefügestrukturen verglichen. Dabei zeigte sich, dass bei der erfindungsgemäßen Legierung nur geringe Gehalte an Mg2Si-Phasen gebildet wurden. Die Rekristallisationstemperatur war bei der erfindungsgemäßen Legierung ebenfalls deutlich erhöht. Ferner war die Anzahl der Beta-Al-Fe-Si-Nadeln um ca. 80% verringert, was auf eine deutlich verbesserte Duktilität der erfindungsgemäßen Legierung schließen lässt.
- Durch Variation der im Anspruch 1 angegebenen Gusslegierung hinsichtlich der Legierungsgrenzen wurden folgende Ergebnisse festgehalten:
- 1.
- Magnesium: bei Gehalten von über 0,55 % wird während des Vergießens der erfindungsgemäß zusammengesetzte Basislegierung die Oxidationsneigung gefördert. Außerdem konnte bei derartig hohen Mg-Gehalten keine weitere Festigkeitssteigerung festgestellt werden, da sich Mg 2Si-Phasen bildeten.
- 2.
- Eisen: bei Gehalten über 0,2 % wird bei allen nach Anspruch 8 vergossenen Legierungen die Dehnung deutlich herabgesetzt.
- 3.
- Titan: Oberhalb von 0,2 % wurde keine Verbesserung des Gefüges eines nach Anspruch 1 ausgebildeten Gussteils im Hinblick auf die Rekristallisationstemperatur festgestellt.
- 4.
- Indium und Cadmium verkürzen die Kaltauslagerungszeit der erfindungsgemäßen Legierung.
- 5.
- Beryllium vermindert bei Magnesiumgehalten von über 0,4 bis 0,55 Gw% die Oxidationsneigung, die wiederum einen ungünstigen Einfluss auf die Dehnung hat.
- 6.
- Cer erhöht in Aluminiumgusslegierungen der Zusammensetzung nach Anspruch 1 - 4 die Fließfähigkeit und mindert bis zu Gehalten von 0,4% die Klebneigung.
- 7.
- Zink verbessert bis zu einem Gehalt von 3,5 % bei einer nach Anspruch 1 zusammengesetzten Legierung die Formstabilität des Gussteils, bei Gehalten von mehr als 3,5% wurde keine weitere Steigerung der Formstabilität bzw. eine Verringerung der Klebeneigung festgestellt.
- Somit lässt sich die technische Überlegenheit der ausgewählten Parameter für die erfindungsgemäße Aluminiumgusslegierung als Ergebnis einer synergistischen Wirkung der jeweils beteiligten Legierungselemente begründen.
