Plasticity of tensile specimen of 7% copper in aluminium composite K. Raji*, Raj S. Alfred Cecil *Holy Cross College, Tiruchirappalli, Tamil Nadu, India. St. Joseph's College, Tiruchirappalli, Tamil Nadu, India. Abstract 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. Top Keywords Plasticity, Deformation, Stress, Strain and Tensile test.
