Abstract

Fe₇₂B_14.4Si_9.6Nb₄ metallic glass particles and pure Fe particles were separately dispersed into the pure aluminum by the friction stir processing. The microstructure and mechanical properties of the stir zone were analyzed using XRD, SEM, TEM and Vickers hardness tests. As a result, it was found that the Fe metallic glass and pure Fe particles can be uniformly dispersed into the pure aluminum by friction stir processing and the mechanical properties of the stir zone can be improved due to the formation of precipitates.
