“…6 interface of TiC and Al produced by infiltration, he observed that in water quench composite Al 3 Ti was barely observed, coarse grain results in a decrease in hardness, adding magnesium will improve the wettability property which reduces defects like pours and other crystal defects. T. Albert et al 25 studied on characterization and preparation of titanium carbide (TiC) reinforced aluminium (Al) composite by powder metallurgy technique and provides the information that TiC and Al interfacial reaction are good below 600 °C hence strength and hardness of the composite will improve with an increase in TiC content. But the number of pores increases as density decreases due to heterogeneous structure of the Al and TiC due to the frittage at 550 °C in the meteorological furnace.…”

The current study focuses on the effect of the different ceramic reinforcement on the aluminium composite. The pros and cons of AMMCs are studied. In SiC reinforced composite’s wear resistance, tensile strength and hardness will be improved, as it acts as an obstacle to the dislocation of atoms. B4C reinforced composites form more pores and agglomeration by the increase in B4C content however the hardness improves at the expense of ductility. TiC reinforced composite’s interfacial bonding is good below 600 °C and the coefficient of thermal expansion reduces by increasing TiC weight percentage also mechanical properties like tensile and compressive strength improves. Al2O3 reinforcement will make grains finer hence adding Al2O3 improves the mechanical properties of the composite and it doesn’t react with the matrix at high temperature. ZrO2 reinforcement will improve the hardness and wear resistance although primary wear happens due to micro-cutting and oxidation. As mentioned each reinforcement has both advantages and disadvantages, based on the application required reinforcement will be selected.

“…Aluminum and Titanium alloys are widely used in automotive applications due to their specific properties. Al and its alloys are characterized by high specific strength, good stiffness, and good wear resistance [1], whereas Ti and its alloys exhibit high specific strength and stiffness, very high corrosion resistance, and biocompatibility. These properties make Ti an excellent choice for applications that range from biomedical to aerospace [2].…”

Metal/metal composites represent a particular class of materials showing innovative mechanical and electrical properties. Conventionally, such materials are produced by severely plastically deforming two ductile phases via rolling or extruding, swaging, and wire drawing. This study presents the feasibility of producing metal/metal composites via a capacitive discharge-assisted sintering process named electro-sinter-forging. Two different metal/metal composites with CP-Ti/AlSi10Mg ratios (20/80 and 80/20 %vol) are evaluated, and the effects of the starting compositions on the microstructural and compositional properties of the materials are presented. Bi-phasic metal/metal composites constituted by isolated α-Ti and AlSi10Mg domains with a microhardness of 113 ± 13 HV0.025 for the Ti20-AlSi and 244 ± 35 HV0.025 for the Ti80-AlSi are produced. The effect of the applied current is crucial to obtain high theoretical density, but too high currents may result in Ti dissolution in the Ti80-AlSi composite. Massive phase transformations due to the formation of AlTiSi based intermetallic compounds are observed through thermal analysis and confirmed by morphological and compositional observation. Finally, a possible explanation for the mechanisms regulating densification is proposed accounting for current and pressure synergistic effects.
