Aluminium-based metal matrix composites were synthesized from Al-TiO2-Gr powder mixtures using the powder metallurgy technique and their forming characteristics were studied during cold upsetting.Green cylindrical compacts of pure Al,Al-5wt%TiO2,Al-5wt%TiO2-2wt%Gr,and Al-5wt%TiO2-4wt%Gr were made using a 400-kN hydraulic press equipped with suitable punch and die and by sintering at(590±10)°C for 3 h.Cold upset forging tests were carried out,the true axial stress(σz),the true hoop stress(σ?),and the true hydrostatic stress(σm)were evaluated and,their behavior against the true axial strain(εz)was also analyzed.It is observed that the addition of5wt%TiO2into the Al matrix increasesσz,σ?,andσm.The addition of both TiO2and Gr reinforcements reduces the densification and deformation characteristics of the sintered preforms during cold upsetting.Microstructure analyses of the as-sintered and cold upset forged specimens also were carried out to substantiate the experimental results.
