Aluminum ALloy Ash Composite

1. Aluminum Alloy- Ash Composites

2. Aluminum
 A Chemical Element in the Boron group
 Its Symbol is Al
 Atomic Number of Al is 13
 It is a Silvery white, Soft & Ductile Metal
 Al is the 3rd most abundant element available (after oxygen
and silicon)
 It has low density and ability to resist corrosion
 Also Durable, Light weight and Malleable

3. Alloy
 A metallic material that is obtained by Chemical
combination of different elements
 Pure metals are rarely used
 Typically alloys have good mechanical properties than
pure metals
 In Aluminum Alloy the predominant element is
Aluminum with the addition of Copper, Magnesium,
Manganese, Silicon, Tin and Zinc
 They are used in applications where light weight and
corrosion resistance is required

4. Ash
 It is a fine powder produced from burning of Coal
 They are spherical shaped balls, finer than cement
particles
 It is a byproduct of coal based power plants
 Tons of coal is burned daily in the industries, Tons of
Fly ash is produced daily

5. Composite
 The combination of Metals, Polymers or Ceramics in such a
way to get our desired properties
 Better properties than either materials
 Good strength to weight ratio, toughness
 Matrix:
◦ Polymer Matrix Composites
◦ Ceramic Matrix Composites
◦ Metal Matrix Composites
 Reinforcements:
◦ Particle Reinforced
◦ Fiber Reinforced

19. Mechanical Properties

21. Conclusion
 No formation of any intermetallic compounds due to interfacial reaction
 The fly ash particles were thermodynamically stable at the compo-
casting temperature
 The majority of the fly ash particles were located in intra granular
regions
 The fly ash particles were dispersed homogeneously in the AMCs
 The interface between the aluminium matrix and fly ash particle was
clear and the bonding was proper
 The incorporation of fly ash particles into semi solid aluminium alloy
improved the wettability
 The addition of fly ash particles enhanced the micro hardness and
tensile strength of the AMCs
