“…The study of the structure, properties of composite materials containing carbon nanotubes has been devoted to many articles [5][6][7][8] . Of great interest is the introduction of carbon nanotubes (CNT) into metal matrices, such as Cu 9,10 , Mg [11][12][13] , Al [14][15][16][17] , Ni [18][19][20][21] . One promising material of the metal matrix is Ti and its alloys.…”

The aim of the work was to study the effect of preliminary mechanical activation of titanium powder mixtures with the carbon nanotubes on a possibility of realization of the self-propagating interaction of reagents in the mode of dynamic thermal explosion and influence on phase composition and morphology of the formed products. It was found that after 2 min. mechanical activation, mechanocomposites of various sizes of irregular shape are formed, some of which are lamellar. There are no carbon nanotubes on the surface of titanium particles, which indicates their incorporation into the volume of mechanocomposites. The thermal explosion in activated samples of composition Ti+4% carbon nanotubes is realized starting from 1.5 min of mechanoactivation. The nature of the thermal explosion varies with the increase in the time of preliminary mechanical activation. After 3 min. of mechanoactivation in the sample at 346°C, the preliminary smooth heat release starts at a temperature of 441°C, and a thermal explosion occurs, the maximum temperature is 930°C. The phase composition of the products of the thermal explosion of the system under investigation is practically independent of the time of the preliminary mechanical activation. When the mechanical activation time is increased from 1.5 to 7 min., the products of the thermal explosion are titanium and titanium carbide.

“…Especially they are predicted as ideal reinforcement for manufacturing of aircrafts and sports goods, duetotheirhighaspectratio,strength,elasticmodulusand low density [3,4]. For instance,CNTs have shown to possess the highest elastic modulus (>1 TPa) in axial direction among all the materials found in the nature [5].There is much work done in investigating these properties of SWCNT.From the latest researches it is found that the Tensile strength of nanotubes can be up to 150 GPa, which is around 10-50 times higher than the steels of highest ultimate strength.Also there were many reports regarding how much effort has so far been rendered to the study of the various aspects of nanotubes such as buckling, mechanical, chemical,electrical and electrsonic, properties [6][7][8]. Researchers have concentrated their work on the utilization of such effective materialsfor macroscopic (and microscopic) applications.…”

“…Stein et al suggested that ultrasonication prior to milling can improve dispersion, resulting in a homogeneous distribution of CNTs inside the matrix particles at the scale of a few micrometers, while requiring shorter milling times. 26 To improve wettability of CNT-Al MMC in melt Al during a consolidation process, Ko et al investigated…”

Low temperature synthesis of carbon nanotube-reinforced aluminum metal composite powders using cryogenic milling

temperature synthesis of carbon nanotube-reinforced aluminum metal composite powders using cryogenic milling. "J. Mat. Sci. 29, 2644(2014 Carbon nanotube (CNT)-reinforced aluminum composite powders were synthesized by cryogenic milling. The effects of different cryogenic milling parameters and CNT contents on the structural characteristics and mechanical properties of the resulting composite powders were studied. Detailed information on powder morphology and the dispersion and structural integrity of the CNTs is crucial for many powder consolidation methods, particularly cold spray (CS), which is increasingly utilized to produce metal-based nanocomposites. While all of the produced composite powders exhibited particle sizes suitable for spray application, it was found that with increasing CNT content, the average particle size decreased and the size distribution became narrower. The dispersion of CNTs improved with milling time and helped to maintain a small Al grain size during cryogenic milling. Although extensive milling allowed for substantial grain size reduction, the process caused notable CNT degradation, leading to a deterioration of the mechanical properties of the composite.
