Modeling of Flow Curve for 2219Al Alloys Microalloyed with Cd
Subscribe/Renew Journal
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.
