“…[73b] It has also been observed that inhomogeneous material density can be the source of preform deformation. There are some solutions to overcome this problem, one of them is the superposition of the sintering driving forces by hot pressing [64,65,75,76] or hot isostatic pressing. [77]…”

This review paper deals with flaws in aluminum-alumina composites and FGMs induced by their manufacturing processes. Aluminum-alumina composites have been studied for many years as potentially interesting materials for applications, for example, in the automotive sector due to their enhanced mechanical strength, wear resistance, good heat conductivity and low specific weight. The focus here is on the interpenetrating phase composites (IPCs) manufactured by infiltration of porous alumina preforms with molten aluminum alloys. The primary objective is to provide an updated overview of research findings on a variety of flaws occurring at different stages of the manufacturing processes. Some precautions on how to avoid processing induced flaws in aluminum-alumina bulk composites and FGMs are mentioned.

“…As a new rapid sintering technology with a high sintering speed, high reproducibility, safety, and reliability, SPS is receiving increasingly attention and widely used to fabricate the functionally graded materials, metal matrix composites and intermetallics [7][8][9][10] . In previous work [11] , we have applied the SPS process to the fabrication of binary γ-TiAl intermetallic.…”

Using spark plasma sintering(SPS) technique, TiC particle reinforced γ-TiAl composites were prepared with varying weight fraction of TiC powders. The effects of the TiC fractions and distributions on the properties of the composites were investigated. The composite containing 7wt% TiC had the optimum three-point bending strength of 842 MPa,which was 200 MPa greater than that of the unreinforced γ-TiAl intermetallic. The degradation of the bending strength occurred in the composites containing more than 7wt% TiC and this was believed to be attributed to agglomerated particles of TiC, which acted as crack initiation and propagation sites. The increase of strength in TiC reinforced IMCs came from the grain refinement and the interaction of dislocations with the reinforcing particles. The bending strength of the IMC containing 7wt% TiC was theoretically estimated to increase by 85 MPa and 200 MPa, respectively, by the grain refi nement and dislocation strengthening, the total of which was almost in accordance with the improvement in that of the unreinforced γ-TiAl intermetallic when considering normal estimation errors.
