Plastic deformation characteristics of sap type alloys

K.Raji, S.Alfred Cecil Raj

Grain refinement is well known to influence the mechanical properties of materials, especially the strength characteristics. The promising and excellentmethod 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 carefullymonitored to get outstanding mechanical properties. This paper explains the study of tensile specimen after its sintering, compaction and extrusion characteristics and process.
