Results reveal that alloying zirconium in the evaluated SMA samples exhibits an excellent grain refinement up to 0.15 wt.%. Further, higher additions of Zr ≥ 0.2 wt.% lowers the grain refinement efficiency due to precipitates agglomeration. Larger the size and volume fraction of Al3Zr precipitates led to higher transformation temperatures. Tensile properties were improved with Zr-doping, resulting enhancements in the maximum tensile strength and ductility with the addition of 0.15 wt.% Zr. The alloy with 0.05 wt.% of Zr-dope showed a good pseudoelastic strain recovery of deformation strain and then lowered by retaining large residual strain, indicating deterioration in the pseudoelasticity of SMAs. © 2022 IOP Publishing Ltd.Beryllium alloysBinary alloysCopper alloysDeteriorationElasticityGrain refinementGrain size and shapeTensile strengthTernary alloysZircaloyAl3zr precipitateExperimental investigationsGrains refinementMicrostructure transformationsPseudoelastic behaviorsPseudoelasticitySeismic applicationTransformation temperaturesZirconium dopingΒ 1-type cu-al-be alloyAluminum alloys
