This paper will summarize the fatigue and elastic modulus advantages of particle reinforced aluminium alloys over conventional alloys. In addition, further property characteristics in terms of elevated temperature performance will be outlined. Recent developments in this field will be discussed including those that have extended the size, complexity and availability of components that can be manufactured from these materials. The capability of shaping technologies via as-HIP powder, forging and extrusion processes have been extended. The ability to manufacture components with high surface finish and tolerances will be discussed including machining & coating capabilities. The paper will also establish the importance of practical net shape fabrication and finishing techniques to allow cost effective manufacture of components.
