Właściwości mechaniczne kompozytów na osnowie stopów Al-Mg-Si wzmacnianych cząstkami $Al_2O_3$

Abstract

This paper presents the analysis of mechanical characteristics of deformation (σ-ε) of composites based on AA6xxx aluminium alloys reinforced with $Al_2O_3$ particles of 10 and 20 μm in diameter in amounts 10 and 20 vol.%. The influence of deformation temperature and strain rate on the flow stress values, at room and elevated temperatures, as well as selected mechanical properties and structure evolution have been established.
