Abstract
Shape Memory Alloy (SMA) merupakan paduan logam yang
mampu kembali pada bentuk awal setelah dideformasi. Aplikasi
paduan Cu-Zn-Al merupakan alternatif dari paduan Ni-Ti yang
banyak digunakan pada dunia dirgantara. Penelitian ini,
menggunakan paduan Cu-14,6Zn-7,41Al dengan variasi
temperatur up-quenching solution treatment dan holding time
artificial aging terhadap struktur mikro, kekerasan, dan shape memory effect. Pengujian yang dilakukan OES, XRD, melatografi, kekerasan, DSC, dan SME. Hasil pengujian struktur mikro pada penlitian ini adalah terdapat fasa α, β, β’, dan γ pada semua spesimen kecuali pada variasi temperatur 105℃ tanpa artificial aging tidak terdapat fasa α. Nilai kekerasan tertinggi terdapat pada spesimen dengan variasi temperatur 105℃ dengan holding time 95 menit dengan nilai 326,33 ± 1,25 VHN. Nilai kekerasan meningkat seiring bertambahnya holding time artificial aging.Nilai SME recovery tertinggi yaitu variasi temperatur 105℃ tanpa artificial aging dengan nilai 90%.

Shape Memory Alloy (SMA) is a metal alloy that is able to return
to its original shape after being deformed. Application of Cu-Zn-
Al alloy is an alternative to Ni-Ti alloy which is widely used in
aerospace. The alloy used was Cu-14,6Zn-7,41Al with variations
in temperature up-quenching solution treatment and holding time
artificial aging on microstructure, hardness, and shape memory
effect. The test were OES, XRD, melatography, hardness, DSC, and
SME. The results of the microstructure testing contained in this
study there were α, β, β’, and γ phases in all specimens except for
the temperature variation of 105°C without artificial aging, there
was no α phase. The highest hardness value in this study was found
in specimens with a temperature variation of 105°C with a holding
time of 95 minutes, with a value of 326.33 ± 1.25 VHN. The
hardness value increased as the artificial aging holding time
increased. The highest SME recovery value was the temperature
variation of 105°C without artificial aging with a value of 90%.
