Plasticity of tensile specimen of 7% copper in aluminium composite

Grain refinement is well known to influence the mechanical properties of
materials, especially the strength characteristics. The promising and excellent method
for grain refinement is a high plastic deformation process and it produces the homogeneous
nano grain material which exhibits very high strength and limited ductility. Sintering is
a complex process for heating powder metal because the final properties of the P/M
parts are direct functions of the heating environment. Hence sintering process is carefully
monitored to get outstanding mechanical properties. This paper explains the study of
tensile specimen after its sintering, compaction and extrusion characteristics and process.
