A current topic of concern in the investigation of dispersion-hardened, rapidly solidified aluminum/transition metal alloys, both in their as-cast and wrought forms, is the development of new or improved combinations of properties through the use of extended alloys and novel processing techniques. Microstructures of materials produced by spray, chill, or weld methods generally contain the features of conventional casting, although on a finer scale. The models by Jones and by Garrett and Sanders for the classification and formation of the solidification structures are described, and a variety of as-cast structures and fracture surface are presented. Several consolidated/fabricated microstructures are also presented. Some interrelationships between processing variables, product microstructures, and mechanical properties such as notched tensile strength and yield strength are clarified. Fracture surfaces of these fabricated materials are described, as well as the effect of microvoids on fracture.
