||One means to enhance the (mechanical) properties of light metals such as aluminum and magnesium is by employing them as composites rather than as monolithic alloys. There is a regaining interest in these metal-matrix composites, amongst others triggered by the use of nano-particle additions (oxides, carbides, nitrides,…) which by their particular morphology induce distinct effects in the composite material in relatively minor amounts. One of the challenges in the development of these materials is to get the particles properly dispersed, for which the use of external fields (electromagnetic, ultrasonic, mechanical shearing) is key. The symposium is meant to address recent advances and review the state-of-the-art in the field of light-metal matrix (nano)-composites. This covers conventional as well as explorative particle additions, powder- as well as melt-metallurgical production routes, modeling as well as experimental contributions, and basic research as well as industrialization and application.
