Abstract

Das Einsatzverhalten dünnwandiger, monolithischer Aluminiumlegierungen, welche in der Luft- und Raumfahrtindustrie eingesetzt werden, wird maßgeblich durch deren Oberflächenmorphologie beeinflusst. Diese setzt sich aus den mechanischen und metallurgischen Randschichteigenschaften sowie der Oberflächentopografie zusammen. In diesem Beitrag wird der Einfluss der Schnittparameter auf die Rauheit, die Mikrostruktur, die Mikrohärte sowie auf prozessinduzierte Eigenspannungen von gefrästem Al 7050 untersucht.

Abstract

The performance of thin-walled, monolithic aluminum alloys used in the aerospace industry is significantly influenced by their surface morphology. This is composed of the mechanical and metallurgical boundary layer properties and the surface topography. The influence of the cutting parameters on surface roughness, microstructure, microhardness and machining induced residual stresses of milled AA 7050 is investigated in this research.
