“…The remaining oxygen is incorporated into the composite powder and this leads to the formation of finely dispersed spinels (MgAl 2 O 4 ) in the bulk material. As the spinels are finely distributed in rather smaller quantities, there is no negative effect expected [22]. Since the powder has non-passivated surfaces after the milling process, there is a possibility of heating.…”

Abstract:The reinforcement of aluminum alloys with particles leads to the enhancement of their mechanical properties at room temperature. However, the creep behavior at elevated temperatures is often negatively influenced. This raises the question of how it is possible to influence the creep behavior of this type of material. Within this paper, selected creep and tensile tests demonstrate the beneficial effects of boron on the properties of precipitation-hardenable aluminum matrix composites (AMCs). The focus is on the underlying microstructure behind this effect. For this purpose, boron was added to AMCs by means of mechanical alloying. Comparatively higher boron contents than in steel are investigated in order to be able to record their influence on the microstructure including the formation of potential new phases as well as possible. While the newly formed phase Al 3 BC can be reliably detected by X-ray diffraction (XRD), it is difficult to obtain information about the phase distribution by means of scanning electron microscopy (SEM) and scanning transmission electron microscopy (STEM) investigations. An important contribution to this is finally provided by the investigation using Raman microscopy. Thus, the homogeneous distribution of finely scaled Al 3 BC particles is detectable, which allows conclusions about the microstructure/property relationship.

“…All materials were solid solution heat treated at 505 • C for at least 60 min, water quenched and naturally aged at room temperature (T4 condition). Details on the preparation of this kind of AMCs are published in [3][4][5]22,24]. Table 1 shows the composition of the five AMCs that are the subject of this paper.…”

“…The effects of HEBM on the structural evolution of Al 2 O 3 reinforced Al-MMCs were studied in detail [22][23][24]. The aluminum peaks tended to broaden as the milling time increased, indicating a decrease in the crystallite size [23].…”

“…The powder extrusion was often adopted in PM technology to help to optimize the reinforcement distribution [13][14][15]24,32], and to improve the properties [33], although the typical lamellarity is often revealed in the longitudinal section in extruded materials [24]. Another advantage of extrusion process is the possibility of making extruded composite products with high dimensional accuracy.…”

Abstract. Aluminum metal matrix composites (Al-MMCs) with Al 2 O 3 particulates as reinforcement fabricated by the power metallurgy (PM) methods have gained much attention due to their unique characteristics of the wide range of Al 2 O 3 particles addition, easy-operating process and effectiveness. The improved PM techniques, such as the high energy ball milling, powder extruder and high pressure torsion were applied to further strengthening the properties or/and diminishing the agglomeration of strength particles. The formation of liquid phase assisted densi¿cation of compacts to promote the sintering of composites. Complex design of Al 2 O 3 particles with other particles was another efficient method to tailor the properties of Al-MMCs.

The research and development of new materials such as particle-reinforced aluminum matrix composites (AMCs) will only result in a successful innovation if these materials show significant advantages not only from a technological, but also from an economic point of view. Against this background, in the Collaborative Research Center SFB 692, the concept of an integrated technology, user, and market analysis and forecast has been developed as a means for assessing the technological and commercial potential of new materials in early life cycle stages. After briefly describing this concept, it is applied to AMCs and the potential field of manufacturing aircraft components. Results show not only technological advances, but also considerable economic potential-the latter one primarily resulting from the possible weight reduction being enabled by the increased yield strength of the new material.
