Abstract
Shape Memory Alloys (SMA) merupakan material yang dapat balik ke bentuk semula setelah mengalami deformasi mekanik. Material SMA yang biasa digunakan, yaitu paduan Ni-Ti. Namun, biaya yang mahal membuat perlu adanya material alternatif, salah satunya Cu-Zn-Al. Beberapa penelitian terkait Cu-Zn-Al Shape Memory Alloys memiliki sifat mekanik yang kurang baik. Maka perlu adanya penelitian lebih lanjut terkait proses heat treatment Cu-Zn-Al Shape Memory Alloys. Pada penelitian ini paduan Cu-21Zn-5Al diberi perlakuan panas dengan variasi temperatur annealing (425;550;600℃) dan media pendingin (Brine;Dry Ice). Proses annealing berpengaruh terhadap sifat mekanik dan struktur mikro pada material uji. Media pendingin berpengaruh terhadap laju pendinginan saat solution treatment. Pengujian pada penelitian ini, diantaranya uji kekerasan, uji metalografi, uji XRD, uji DSC dan uji SME. Dari hasil pengujian, didapatkan bahwa pada semua variabel uji memiliki Shape Memory Effect. Variabel yang memiliki recovery paling besar (38,3%) yaitu temperatur annealing 450℃ dengan media pendingin solution treatment menggunakan brine. Selain itu pendinginan paling cepat terjadi pada media pendingin brine.

Shape Memory Alloys (SMA) is a material that can return to its original shape after undergoing mechanical deformation. The most commonly SMA material used is the Ni-Ti alloy. However, it is high cost. so that it is necessary to have alternative materials, for instance Cu-Zn-Al. Several studies related to Cu-Zn-Al Shape Memory Alloys have poor mechanical properties. So there further research required in ordert to determine the heat treatment process of Cu-Zn-Al Shape Memory Alloys. In this study Cu-21Zn-5Al alloys were given heat treatment with annealing temperature variations (425; 550; 600 ℃) and cooling media (Brine; Dry Ice). Annealing process affects the mechanical properties and microstructure of the test material. Cooling media results the cooling rate during solution treatment. Tests in this study include hardness test, metallographic test, XRD test, DSC test and SME test. From the test results, it was found that all the test variables have the Shape Memory Effect. The variable that had the greatest recovery (38.3%) was annealing temperature of 450 ℃ with the cooling solution media using brine. In addition, the most rapid cooling occurs in the brine cooling media.
