The major concern of the design for manufacturability is to accomplish the require deformation without failure of work material. The degree of deformation that can be achieved in a particular metal forming process without creating condition is termed as workability. The present investigation pertains to study the cold workability behaviour of Cu-7%Al-1.8%Si sintered preforms. Cold upsetting of these preforms with various aspect ratios were carried out and the working behaviour of the preforms at various stress state conditions was computed. The analysis measured for different components such as stress formability index and obtained density during secondary deformation as a function of induced strain. Similarly various computed stress ratio parameters with induced strain
