摘要：
In this paper we present a study on the mechanical properties of aluminium alloy, particularly on the nanohardness determined by nanoindentation. The tests are performed onto samples, exposed to the outer space conditions and such that were kept in terrestrial ones. It is evidenced that the absorbed high radiation dose leads to partial crystalline structure degradation, the latter leading to a significant decrease in the hardness test.
