“…For comparison, Fig. 6(a) (20) samples were similar to Al, but the l f of Al(65)-Ti 3 SiC 2 (35) was $0.50, and significantly lower. Thus, at higher concentration, Ti 3 SiC 2 particulates have lubricating effect on the Al-matrix composites.…”

In this paper, we report for the first time, the synthesis and characterization of novel Ti 3 SiC 2 reinforced Al-matrix composites. All the composites were cold pressed and sintered in the temperature range of 700-750°C for 5-30 min in an inert Ar atmosphere. Microstructure analysis by scanning electron microscopy and phase analysis by x-ray diffraction confirmed that there was minimal interfacial reaction between Ti 3 SiC 2 particles and Al. The addition of Ti 3 SiC 2 enhanced the mechanical performance of the composites. For example, the pure Al samples had a yield strength of 97 ± 6 MPa, where as the volume fraction of Ti 3 SiC 2 was increased to 5 and 10 vol.% in the composites, the yield strength increased significantly to 212 ± 27 and 273 ± 52 MPa, respectively. As the volume fraction of Ti 3 SiC 2 was further increased to 20 and 35 vol.%, the yield strength mildly increased to 278 ± 48 MPa, and then decreased to 134 ± 20 MPa, respectively. The decrease in yield strength after 35 vol.% Ti 3 SiC 2 addition in the Al matrix was attributed to the presence of higher amount of porosity in these samples. The addition of Ti 3 SiC 2 particles also had a beneficial effect on the tribological performance of these composites against alumina substrates.

“…The NiTi SMA layer provides high mechanical damping and toughness through energy dissipation as a result of superelasticity, [30] and acts as an intermediate layer between the PMC and the ceramic-metal (NiTi) composite (CMC) in our multilayer hybrid composite. While superelasticity in equiatomic NiTi degrades around 150 C, Ni-rich alloys can demonstrate superelasticity up to 220 C [31] and high temperature SMAs of the type NiTiX (X ¼ Hf, Zr, Pd, Pt, Au) up to 500 C. [30] Hu et al, [32] and Kothalkar et al, [33] have demonstrated several benefits of combining NiTi with carbide ceramics in a CMC, including the ability to control residual stresses through the constituent composition, phase morphology, and thermomechanical conditioning [33] Vascularization of NiTi provides enhanced cooling capability compared to the PMC alone. The thermal conductivity of NiTi is in the range of 12-16 Wm À1 K À1 [34] (isotropic) compared to only 0.4-0.6 Wm À1 K À1 in the through-thickness direction for the PMC.…”

Microvascular shape memory alloy (SMA)-polymer matrix composite (PMC) hybrid materials are fabricated using the Vaporization of Sacrificial Components (VaSC) technique. Two types of sacrificial materials are used: Mg wires in the SMA (nickel titanium) and poly(lactic acid)/tin(II) oxalate fibers in the PMC (glass fiber/epoxy). These sacrificial materials survive the initial solidification of the host materials, then are vaporized during a final thermal treatment to reveal the vascular network. The effect of VaSC on composition and transformation temperatures of the SMA are examined. Active cooling through the vascular network maintains temperature in the PMC below the glass transition temperature (152 C) at heat fluxes as high as 300 kW m À2 , while this temperature is exceeded without cooling at just 10 kW m À2 .

“…One particular member of this class, Ti 3 SiC 2 Ti 3 SiC 2 exhibits a high melting temperature, high electrical and thermal conductivities, and an excellent resistance to oxidation and thermal shock. In addition, this material possesses unusual mechanical properties, such as easy machinability, a high Young's modulus, an ultra-low friction coefficient [2][3][4][5][6][7][8], and nonlinear elasticity in strain cycling, which makes it a potential candidate for practical applications as a high-temperature structural material [9][10][11], damping material [12], self-lubricating material [13], etc. Recently, MAX phases were proposed as candidates in advanced nuclear reactors [14,15] with particular potential applications as fuel coating or cladding material for future fission reactors [16,17].…”
