The paper focuses on the creep behaviour of age-hardenable particle-reinforced aluminium alloys, which were produced by means of mechanical alloying. The differences in the creep behaviour compared to the unreinforced alloy were documented. Furthermore, the mechanisms affecting the materials were discussed. As a result of the powder metallurgical production route the AMCs are characterised by a very fine-grained structure, a high concentration of grain boundaries, phase interfaces, and a large number of dislocations. All these microstructural properties lead to increased precipitation kinetics of the matrix alloy. Hence, in the recent work the possibility to reduce the for the creep behaviour of the AMCs detrimental diffusion by adding boron was investigated. To describe the microstructural influence of boron, the arising microstructure was analysed i.e. by Raman spectroscopy, which provides an important contribution to the spatial resolution of the newly formed phase Al3BC.
