Review on Using Powder Metallurgy Method for Production of Metal-Based Nanocomposites

Abstract

Due to the constant need for metal matrix nanocomposites (MMNCs), which are used in industrial applications such as automotive, aerospace, and many others, and therefore many researchers, are interested in making them nanocomposites with better performance, studies are continuing to improve their properties. In contrast to other versatile conventional production methods, powder metallurgy (PM) method is highly effective in eliminating porosity, wetting and casting defects. In this review, an in-depth discussion of the different MMNCs fabricated by the PM method with an explanation of the different stages of preparation of these nanocomposites such as powder production, pressing and sintering was discussed. Also, the different factors affecting milling and sintering processes were reviewed. Finally, the advantages, disadvantages, and more common applications of PM in the preparation of these nanocomposites mentioned above were discussed in some detail.

Synthesis of hydroxyapatite from eggshells via wet chemical precipitation: a review

“…HA is characterized by low mechanical properties, which limit its application. 6,[39][40][41][42][43][44] Many papers have reported the possibility of enhancing its mechanical properties through mixing with additives or other materials to form composite materials. For instance, Mobasherpour et al studied the effect of the addition of zirconia and alumina, 45 while Mukherjee et al studied the effect of nanocarbons on the mechanical properties.…”

Investigation of a hybrid manufacturing method involving selective laser melting and sintering

“…PM, on the other hand, involves heating compacted powder to a temperature below its melting point to cause particle bonding. 6,7 The process parameters, such as laser power, scanning speed, and powder bed temperature, were varied to study their effect on the final product's quality. [8][9][10][11] The performance of the hybrid manufacturing method was evaluated using several metrics, including material microstructure, dimensional accuracy, mechanical properties, and surface roughness.…”
