Effect of the Deformation Scheme on the Structure and Properties of Hot-Forged Aluminum-Matrix Composites

  • THEORY AND TECHNOLOGY OF FORMING PROCESS

Powder Metallurgy and Metal Ceramics Aims and scope

The structure and mechanical properties of aluminum-matrix composites, produced by hot forging of billets consisting of Al and 15 wt.% TiC–20% Al master alloy powder mixture, are investigated. Cylindrical and hollow cone billets are used for forging. It is shown that both strength and hardness of the composites produced from conical billets noticeably exceed those of the materials produced from cylindrical billets. In comparison with cylindrical billets, the use of conical billets for forging leads to an increase in (i) the intensity of deformation and (ii) the microhardness of the matrix phase.
