Uniaxial tensile tests were conducted on cast and homogenized 2219Al alloys microalloyed with varying contents (0 to 0.1 wt.%) of Cd. Flow curves were generated and Hollomon equation was modeled. The influence of Cd additions on flow parameters like strain hardening exponent, strength co-efficient, elastic and plastic strains was investigated. Resilience and toughness values were estimated both by equation modeling and area integration methods.

Abstract


Uniaxial tensile tests were conducted on cast and homogenized 2219Al alloys microalloyed with varying contents (0 to 0.1 wt.%) of Cd. Flow curves were generated and Hollomon equation was modeled. The influence of Cd additions on flow parameters like strain hardening exponent, strength co-efficient, elastic and plastic strains was investigated. Resilience and toughness values were estimated both by equation modeling and area integration methods.
