Title : Study the microstructure, hardness and wear behaviour of aluminium 1050-H4 reinforced by corn cob particles.

Abstract:

Composite materials belong to the advanced material class, with modification in mechanical properties along its dimensions. Aluminium-corn cob particles were formed using casting method. Two different corn cob particles sizes of -0.425 mm and +0.425 mm were used to reinforce the aluminium alloy to produce the composites. Samples characterization was performed using SEM. Hardness and tribology tests were performed according to ASTM E384 and ASTM G99 standards . The results will be analysed and discussed.

Audience Takw Away Notes:

• This study will show how aluminum can be reinforced using organic materials, which is a cost effective method
• Audience will learn the effect corn-cob on mechanical properties, microstructure and wear behavior of aluminum reinforced by this particles
• This method can be used by other researchers to reinforce the aluminum 1050 H4
