Abstract

A fracture criterion is necessary to approximate the strain path in the workability diagram to predict a safe zone for the metal-forming process. For the present study, Oyane's fracture criteria are applied to establish a workability characteristic for the chosen Aluminium (Al) composite. Al with 4Fe3C composite was considered in this study with the 2 and 4% Cu increment; pure Al is also considered. The preforms are prepared through the primary powder metallurgy technique and further deformed using cold forging under two different lubricant conditions. A fracture model (FM) is predicted for each category, and it was found to have a good agreement under the influence of the compositions. However, under the effect of lubricants, except for pure Al but for all other composites, it agrees well with the predicted FM. Later, the analysis of variance (ANOVA) study was carried out to quantify the effect of the influential parameters on the effective strain at fracture.
