“…The mechanism of load transfer strengthening has a leading role in interpreting the influence of CNTs on the strengthening of Cu/CNT composites. Duong et al 49 observed that, in Cu/CNT composites, the enhanced hardness and tensile strength are attributed to the interfacial bond strength between the strengthening materials (CNTs) and Cu matrix. Therefore, the increment in hardness with the CNT content is related to the participation of the more interfaces between the Cu matrix and CNTs, which act as a bridge to transfer the mechanical loads, and therefore increase the elastic modulus ( ).…”

In this study, we analyze the influences of carbon nanotube (CNT) addition on the martensite transformation and internal friction of Cu–Al–Ni shape-memory alloys (SMAs). X-ray diffraction and differential scanning calorimetry results demonstrate that Cu–13.5Al–4Ni–xCNT (x = 0, 0.2, 0.4, 0.6, and 0.8 wt%) SMA/CNT composites exhibit a $${\upbeta }_{1}({\mathrm{DO}}_{3})\rightleftarrows {\upbeta }_{1}^{\mathrm{^{\prime}}}(18\mathrm{R})$$ β 1 ( DO 3 ) ⇄ β 1 ′ ( 18 R ) martensitic transformation. The martensitic transformation temperatures and transformation enthalpies of the martensitic transformation peaks for the Cu–13.5Al–4Ni–xCNT (x = 0–0.8 wt%) composites gradually decrease with the increase in the amount of CNT addition. Compared to the Cu–13.5Al–4Ni SMA, the Cu–13.5Al–4Ni–xCNT (x = 0.2–0.8 wt%) SMA/CNT composites exhibit significant improvements in the amount of dissipation of energy (storage modulus ($${E}^{\prime}))$$ E ′ ) ) and mechanical strength. However, the tan δ of the internal friction peak gradually decreases with the increase in the CNT content above 0.6 wt%. The reduction in tan δ is attributed to the decrease in the magnitude of the austenite-to-martensite transformation and precipitation of γ2 (Cu9Al4) phase particles, which impede the interface motion in between the parent/martensitic phase and martensitic phase.

“…TiC improves the sliding wear resistance of aluminium alloys. TiC is the hard particle that resists the destructive action of abrasion and protects the surface, so by increasing its percent, the wear resistance enhances [25]. SEM micrographs of worn surfaces of specimens under 10 N applied load is presented in Fig.…”

Al-TiC nanocomposites are prepared by powder metallurgy technique. The effect of milling time and TiC percent on the mechanical properties and microstructure are studied. Nano TiC powders with 5, 10, and 20 wt. % is added to the Al matrix. The mixed powders are mechanically milled by a 35:1 ball to powder ratio and 110 rpm for 6, 12, 24, and 48 hr. milling time (MT). Mixed powders are compacted by a uniaxial press under 600 Mpa and sintered at 600 °C for 1 hr. in a vacuum furnace. According to Archimedes' principle, the density was estimated, which indicated it is decreasing for 6 hr. milling time, followed by an increase for 12 and 24 hrs., then another decreasing for 48 hrs. The addition of nano TiC increases the density values gradually by increasing its percent. Both the phase composition and microstructure of both composite powders and sintered samples are examined using XRD & FE-SEM, respectively. XRD results indicated forming the aluminum carbide (Al4C3) phase that is formed during the sintering process. The microstructure shows the homogeneous distribution of TiC on the Al matrix and the reduction of Al particle size by increasing both milling time and TiC percent. Hardness, compression strength, and wear resistance are improved by increasing TiC content and MT up to 24 hours. Al-20 wt. % TiC composite with 24 hr. milling time exhibited the highest hardness (196.5667 HV) and the lowest wear rate (0.001 g/min).
