“…Generally, using aluminum powders as a matrix, microstructure can be developed very well with this method. Sinter þ forging process, also called a new manufacturing method, provides high dimensional precision in the manufacturing of industrial parts [13,14,16,17]. For this reason, this method is used for bulk materials in industrial applications.…”

“…Today, new generation of aluminum matrix composites with a variety of particle reinforcements are being produced by different manufacturing methods and the effect of reinforcements on the physical and mechanical properties of the AMCs are evaluated in detail with the goal of developing AMCs with properties suitable for structural applications [15][16][17]. In this research, AMCs reinforced with titanium nitride (TiN) and alumina (c-Al 2 O 3 ) are investigated with the aim to be used as linkages, connectors in aeronautical applications where high hardness and high wear resistance along with high resistance to compression and bending loads are needed.…”

“…AA 2319). In many of the studies, fine ceramic reinforced aluminum composites were generally produced by reactive metal infiltration and/or by melting process very similar to in situ reaction [17][18][19][20][21][22][23]. Based on our scientific and experimental knowledge and our agreement with the aeronautic research team, we have been developing the method "Sinter þ Forging and/or Thixoforming," for the manufacture of hard ceramic particle reinforced composites.…”

“…simple powder metallurgy route is followed by the final processing as hot forging and or thixoforming as we have explained in detail in our former publications e.g. [2,4,5,[7][8][9][13][14][15][16][17][18]. Again, we have been developing this method for mass production of the connection (knuckle) parts of different sizes in aeronautical/aerospace engineering applications as a low cost and efficient manufacturing process.…”

Hybrid intermetallic composites (HICs-aluminum based matrix, new hybrid design) reinforced with titanium nitride (TiN) and alumina (c-Al 2 O 3 ) were designed and manufactured through the innovative combined method of sinter þ forging. This method results in highly dense materials with, in general, improved mechanical properties. In the composites TiN content was varied (10, 20 and 30 wt %) but c-Al 2 O 3 content was kept constant at 10 wt%. Additionally, 5 wt% each of Cu and Ni were mixed in to improve processing of the composites. The mechanical properties were specified by different destructive test methods (wear performance, micro hardness, quasi-static compression, three-point bending tests). Wear performance was investigated by scratch experiments. Scanning electron microscopy (SEM) was used to determine the microstructure, interface characteristics and the fracture surfaces. The SEM analysis yielded that TiN powders were located at the grain boundaries and this can be attributed to the improvement observed in the mechanical properties and wear performance with the addition of TiN.
