“…The cold workability parameters under tri-axial stress state condition of powder metallurgy composite preforms, namely, the true axial stress (r z ), the true axial strain (e z ), the hoop strain (e h ), Poisson's ratio (a), relative density (R) and axial stress (r z ), the true hoop stress (r h ), true hydrostatic stress (r m ), true effective stress (r eff ), the formability stress index (b r ) and true effective strain (e eff ) are elaborately explained from previous works [33][34][35][36][37][38][39][40][51][52][53][54].…”

“…They investigated that the effect of relative density on the forming limit of P/M compacts in upsetting. The cold workability and the strain hardening behavior of porous P/M composites under uniaxial, plane and triaxial conditions have been elaborately analyzed and discussed in the previous works by Narayanasamy et al [34][35][36][37][38][39][40]. Their results have shown that the workability behavior of metals/alloys/composites of P/M components depends on the relative density, the aspect ratio, the preform geometry, the particle size and the percentage of reinforcement for the composites, the die geometry, the lubricants, and the compacting load.…”

Al+2.5%TiO 2 +Gr composites were synthesized through powder metallurgy technique and their workability behavior has been studied under tri-axial stress state condition. The powders were compacted using suitable punch and die in 400 kN hydraulic press and sintered at a temperature of about 590 °C for a period of 3 hours in an electric muffle furnace. The sintered preforms were characterized by XRD and SEM analysis. Then the preforms were subjected to incremental compressive loading of 10 kN until the cracks found at the free surface. The true axial stress (s z ), true hoop stress (s ө ), true hydrostatic stress (s m ) true effective stress (s eff ), formability stress index (β) and stress ratio parameters [(s z /s eff ), (s m /s eff ), (s ө /s eff )] were calculated for all the preforms and these are correlated with the true axial strain (e z ). It is inferred that, the addition of TiO 2 and Gr to the Al matrix material increases the stress ratio parameters and formability stress index (β). A hardness test was also conducted for sintered and cold forged preforms and results are reported.

The investigation on the effect of sintering temperature and time intervals on workability behaviour of Al-SiC powder metallurgy composites during cold upsetting was attempted in the present work. Three levels of sintering temperature and time have been considered to evaluate their effect on workability behaviour. The amount of SiC reinforcement content has been varied as 0%, 10% and 20%. The experimental results were analyzed for workability under triaxial stress state condition as a function of the relative density. The Formability Stress Index (β σ ), the Formability Strain Index (β ε ), stress ratio parameters namely σ θ /σ eff and σ z /σ m were obtained for all the cases. As a result, the exhibited tremendous variations in the various parameters for different sintering temperatures and time intervals were studied and reported.
