“…In this last case, ammonia was incorporated after 2 h of milling, and then millings continued in vacuum until reaching 10 h. The ammonia gas purity was higher than 99.96% (Air Liquide). The water-cooled stainless steel vessel had a capacity of 1400 cm 3 . Etilen bis-stereamide (EBS) micropowder organic wax (3 wt %) was used as a process control agent (PCA) during milling.…”

“…Increasing the use of lightweight alloys (e.g., aluminium) leads to a significant reduction in the overall weight, fuel consumption, and pollution of automobiles and aircrafts [1][2][3][4]. Aluminium has a very low density (2.7 g/cm 3 ), high specific strength, excellent low temperature performance, good formability, and exceptional corrosion resistivity [5,6]. Despite their interesting properties, commercial heat-treated aluminium alloys suffer a remarkable degradation of properties at high temperature.…”

“…[83,86,[88][89][90] However, greater cost, scarce availability, and segregation of these nanoparticulates during processing have been recognized as the major challenges in the development of nanoparticulated AMCs. [86,[91][92][93] In several research studies, AMCs containing conventional ceramic reinforcements have reported many typical defects, such as extreme brittleness, porosity, agglomeration, detrimental interfacial reactions, that adversely restricted their applications. [94,95] To eliminate these defects occurred in the AMCs, many novel Table 1.…”

“…As a result, the exchange between the solid-gas interfaces and solid-liquid interfaces of the particles occur becoming active to the melt and acting as solidification sites. [13,82] matrices. UST was applied to the melt using a niobium probe with a frequency of 17.5…”

“…Schematic of the dispersion of particles by the addition of UST to the casting process[81].Different feeding techniques to add the particles into molten metals for the manufactured of MMCs have been reported by researcher, such as spraying them in the surface of the melt, wrap them as capsules on metallic foil, placing them between the metal as a layered structure and also using perforated containers (niobium cage) placed under the sonotrode[13,22,82,83].Srivastava et al reported the effect of temperature on the fabrication of aluminum reinforced with Al2O3 composites. Temperatures of 700 o C, 725 o C, 750 o C and 775 o C were studied, for each experiment where 300 g of Al6061 was melted and 1wt.…”
