Praveen Kumar full time research scholar enrolment number (15PME004) under the guidance of Dr. Anil Kumar Birru assistant professor and head of Department of Mechanical Engineering NIT MANIPUR 

主　　题：Al-4.5Cu alloy stir casting composites bamboo leaf ash density porosity 

摘      要：Al-4.5%Cu alloy was used as a matrix at2%,4%and6%of bamboo leaf ash(BLA)which was extruded from agro waste and was used as *** composite which was fabricated by stir casting method possessed superior properties due to an effective bonding between matrix and reinforcement *** fabricated composite specimens were subjected to various tests to determine the mechanical properties such as density,porosity,hardness and tensile *** results were compared with basic matrix ***,the OM,SEM with EDAX and XRD analyses were carried out to analyze the dispersion of the reinforced particles in the selected matrix *** was observed that the homogeneous distribution of BLA particles in composites was intragranular in ***,it was also observed that BLA particles were well bonded with matrix alloy with clear *** was also found that the density decreased with increase in mass fraction of BLA particles and porosity increased with increase in mass fraction of BLA *** hardness and tensile strength were increased up to4%of BLA in the composite,with a further increase in BLA content the hardness and tensile strength decreased.
