Bala Narasimha, G.Murigendrappa, S.M.2026-02-052019Materials Science and Engineering: A, 2019, 755, , pp. 211-2199215093https://doi.org/10.1016/j.msea.2019.04.022https://idr.nitk.ac.in/handle/123456789/24568This paper presents an investigation of the effect of zirconium on the properties of polycrystalline Cu-Al-Be shape memory alloy. Mechanical and shape memory properties have been evaluated by varying the compositions of Zr to Cu<inf>88.13</inf>-Al<inf>11.42</inf>-Be<inf>0.45</inf> alloy ranging from 0.05 to 0.4 wt% with step 0.1 wt%. The results unveil reduction in the grain size of 89.18% with the improved tensile strength of 667 ± 30 MPa and ductility of 23.95 ± 0.86% and excellent shape recovery ratio of 100% with the addition of Zr up to 0.3 wt%. Increase in transformation temperatures is observed with the addition of Zr. © 2019 Elsevier B.V.Aluminum alloysCopper alloysGrain refinementGrain size and shapePolycrystalline materialsPrecipitation (chemical)Shape memory effectTensile strengthZirconium% reductionsCu–al-be shape memory alloyGrains refinementGrainsizeMechanical memoryPolycrystallinePrecipitation strengtheningPropertyShape recovery ratiosShape-memory propertiesHydrogen
