Synthesis of bulk nanostructured aluminum alloy component through vacuum plasma spray technique

Formation of Nanocrystalline Matrix Composite during Spray Forming of Al83La5Y5Ni5Co2

“…RECENTLY, the synthesis of Al-RE-TM-based amorphous or nanocrystalline bulk materials have attracted unprecedented interest due to their high specific strength along with improved physical properties. [1][2][3][4][5][6] In general, the bulk amorphous or nanocrystalline material is synthesized by consolidation of pulverized melt-spun amorphous ribbons or gas-atomized amorphous powders in the size range of 10 to 20 lm. [7,8] The amorphization of Al-based alloys involves high cooling rate due to their low glass-forming ability compared to the other systems, e.g., Cu-, Zr-, and Fe-based alloys.…”

Structure and consolidation of rapidly solidified Meso 10 alloy flakes

“…Nano-structured bulk materials, synthesized through different processes, often vary significantly in terms of their mechanical properties, which is attributed to the variance in microstructural features, defects, flaws and porosity levels [29,8]. Using high extrusion ratios and intense deformation that are available with the KOBO method, effective homogenization of the processed material is possible.…”

Mechanical consolidation of rapidly solidified Meso 20 alloy flakes – Structure and mechanical properties

“…Even if a heating pulse occurs due to the intense deformation at a high extrusion ratio, its duration is likely to be short enough to avoid the noticeable coarsening of the fine RS structure. Furthermore, it is commonly known that the microstructure defects, flaws and porosity deteriorate the mechanical properties of PM materials [34,35]. In the consequence of the intense processing at a high extrusion ratio, which is available with the KOBO extrusion method, an effective homogenization of the processed PM material can be expected.…”
