Present study aims to develop computational models for the tensile flow curves of Cast-homogenized 2219Al alloys microalloyed with varying Cd contents (up to 0.1 wt.%). Uniaxial tensile tests were conducted, and flow curves were generated. Influence of Cd contents was investigated, and favorable composition was identified for tensile flow parameters. Flow curves obtained from uniaxial tensile tests were further mathematically modeled through Hollomon equation, by determining the values of strain hardening exponent and strength coefficient, first time for the investigated alloys. Strain hardening exponent and strength coefficient increased (by 23% and 6.1% respectively) with increasing Cd content up to 0.06 wt.%. Elastic and plastic strain values significantly decreased with increasing Cd additions up to 0.06 wt.%. Modulus of tensile resilience and toughness were estimated by two separate computational techniques of area integration and equation modelling. Results obtained by the different methodologies were successfully compared and analyzed. Average plastic strain was observed to be 5.8 times more compared to the average elastic strain of the alloys. Modulus of resilience was observed to be saturated, while tensile toughness followed the identical trend as plastic strain with Cd composition. Tensile toughness of the alloy decreased lowest by 41.8%, when microalloyed with 0.08 wt.% Cd. Trace contents of Cd exhibited to have significant potential to influence flow properties of investigated 2219Al alloy system. Present investigation is expected to provide a helpful analysis and computational model of different tensile flow parameters, to validate manufacturing feasibility and prospective applications of these alloys.
