In den letzten Jahren wurden zunehmend Forderungen nach besonders ökonomischen und damit ökologischen  In recent years, there have been increasing demands for particularly economic and therefore ecological

Emissionsanforderungen gerecht werden müssen. Zudem besteht jeher das Bedürfnis, Motoren möglichst leistungsfähig und verbrauchsarm zu gestalten. Ein entscheidender Faktor bei der Entwicklung von leistungsfähigen und emissionsarmen Emissions requirements. In addition, there is always the need to make engines as powerful and low-consumption. A key factor in the development of high-performance and low-emission
Verbrennungsmotoren sind Kolben, die bei immer höheren Internal combustion engines are pistons, which are always higher
Verbrennungstemperaturen und Verbrennungsdrücken eingesetzt werden können, was im Wesentlichen durch immer Combustion temperatures and combustion pressures can be used, which is essentially by always
leistungsfähigere Kolbenwerkstoffe ermöglicht wird. more efficient piston materials is made possible.
Grundsätzlich muss ein Kolben für einen Verbrennungsmotor eine hohe Warmfestigkeit aufweisen und dabei gleichzeitig möglichst leicht und fest sein. Dabei ist es von besonderer Bedeutung, wie die mikrostrukturelle Verteilung, Morphologie, Zusammensetzung und thermische Stabilität höchstwarmfester Phasen ausgebildet sind. Eine diesbezügliche Optimierung berücksichtigt üblicherweise einen minimalen Gehalt an Poren und oxidischen Einschlüssen. Basically, a piston for an internal combustion engine must have a high heat resistance and at the same time be as light and strong as possible. It is of particular importance how the microstructural distribution, morphology, composition and thermal stability of highly heat-resistant phases are formed. An optimization in this regard usually takes into account a minimum content of pores and oxide inclusions.
Der gesuchte Werkstoff muss sowohl hinsichtlich isothermer Schwingfestigkeit (HCF) als auch hinsichtlich The material sought must be both in terms of isothermal fatigue strength (HCF) and in terms of
thermomechanischer Ermüdungsfestigkeit (TMF) optimiert werden. Um die TMF optimal auszugestalten ist stets eine möglichst feine Mikrostruktur des Werkstoffs anzustreben. Eine feine Mikrostruktur reduziert die Gefahr des Entstehens von Mikroplastizität bzw. von Mikrorissen an relativ großen primären Phasen (insbesondere an primären thermomechanical fatigue strength (TMF) optimized become. In order to optimally design the TMF, it is always desirable to have the finest possible microstructure of the material. A fine microstructure reduces the risk of microplasticity or microcracks on relatively large primary phases (especially primary)
Siliziumausscheidungen) und damit auch die Gefahr von Silicon precipitates) and thus the risk of
Rissinitiierung und -ausbreitung . Crack initiation and propagation.
Unter TMF-Beanspruchung treten an relativ großen primären Phasen, insbesondere an primären Siliziumausscheidungen, aufgrund unterschiedlicher Ausdehnungskoeffizienten der einzelnen Bestandteile der Legierung, nämlich der Matrix und der primären Phasen, Mikroplastizitäten bzw. Mikrorisse auf, welche die Lebensdauer des Kolbenwerkstoffs erheblich senken können. Zur Erhöhung der Lebensdauer ist bekannt, die Under TMF stress, microplasticities or microcracks occur on relatively large primary phases, in particular on primary silicon precipitates, due to different coefficients of expansion of the individual constituents of the alloy, namely the matrix and the primary phases, which can significantly reduce the service life of the piston material. To increase the life it is known that
primären Phasen möglichst klein zu halten. primary phases as small as possible.
Beim verwendeten Schwerkraftkokillenguss gibt es eine When using gravity chill casting, there is one
Konzentrationsobergrenze, bis zu der Legierungselemente eingebracht werden sollten und bei deren Überschreiten die Gießbarkeit der Legierung verringert oder Gießen unmöglich wird. Darüber hinaus kommt es bei zu hohen Konzentrationen von festigkeitssteigernden Elementen zur Bildung großer plattenförmiger intermetallischer Phasen, welche die Concentration upper limit up to which alloying elements should be introduced and, if exceeded, the castability of the alloy is reduced or casting becomes impossible. In addition, too high concentrations of strength enhancing elements lead to the formation of large plate intermetallic phases which cause the
Ermüdungsfestigkeit drastisch absenken. Drastically lower fatigue resistance.
