Fly ash is waste of coal combustion which can be used in Aluminum alloy. In this research Aluminum is mixed with fly ash that used powder metallurgy method. Aluminum powder is produced by Merck German which is in irregular form and has homogeneous particles, while fly ash is got from residual combustion coal in forging section of Politeknik Negeri Sriwijaya (Polsri) mechanical workshop which ...
R. Ganesh Narayanan, IITG Atomization This uses high pressure fluid jets to break up a molten metal stream into very fine droplets, which then solidify into fine particles High quality powders of Al, brass, iron, stainless steel, tool steel, superalloys are produced commercially Types: water atomization, gas atomization, soluble gas or vacuum atomization, centrifugal atomization, rotating disk ...
R. Ganesh Narayanan, IITG Classification of basic bulk forming processes Rolling Forging Extrusion Wire drawing Rolling: In this process, the workpiece in the form of slab or plate is compressed between two rotating rolls in the thickness direction, so that the thickness is reduced.
This research is aimed to analysis the effect of holding time, grain size and compacting pressure parameter against compressive strength of Aluminum-5% fly ash using powder metallurgy method. The irregular form and homogeneous particles of aluminum powder used in this research is produced by Merck German, while fly ash is taken from residual combustion coal in forging process in mechanical ...
R. Ganesh Narayanan, IITG 4.Centrifugal atomization: In this method, one end of the metal bar is heated and melted by bringing it into contact with a non-consumable tungsten electrode, while rotating it longitudinally at very high speeds. The centrifugal force created causes the metal drops to be thrown off outwards. This will then be solidified as spherical shaped particles inside an ...
