Abstract
Paduan Shape Memory Alloy merupakan paduan yang dapat kembali kebentuk maupun ukuran semula setelah dideformasi pada temperatur tertentu. Pada saat ini paduan yang sering digunakan sebagai bahan pembuatan shape memory alloy yaitu paduan tembaga misalnya Cu-Zn-Al dan Cu-Al-Ni, serta paduan Ni-Ti, karena sifak mekaniknya yang cukup baik. Shape memory alloy dapat dibentuk dengan metode casting dan dilanjutkan dengan diberikan perlakuan panas, yaitu homogenizing, annealing, solution treatment dan aging. Kemudian dilakukan beberapa pengujian yaitu pengujian struktur mikro, X-Ray Diffraction, Differential Scanning Calorimetry dan Shape Memory Effect. Dari hasil review paper adanya proses perlakuan panas mempengaruhi struktur mikro yang ada pada paduan shape memory alloy, sehingga berpengaruh juga pada shape memory effect yang dihasilkan. Pada paduan Cu-based, solution treatment dan aging adalah perlakuan panas yang paling mempengaruhi perubahan struktur mikro dan shape memory effect, karena solution treatment mempengaruhi terbentuknya fasa martensit dan aging mempengaruhi terbentuknya fasa α. Pada paduan Ni-Ti perlakuan panas aging dan annealing mempengaruhi perubahan struktur mikro apabila dilakukan pada diatas temperatur 400°C.
======================================================
Shape Memory Alloy is an alloy that can return to its original shape and size after being deformed at a certain temperature. At present alloys that are often used as materials for making shape memory alloys are copper alloys such as Cu-Zn-Al and Cu-Al-Ni, and Ni-Ti alloys, because of their reasonably good mechanical properties. Shape memory alloy can be formed by casting method and followed by heat treatment, which is homogenizing, annealing, solution treatment and aging. Then a number of tests are performed, namely microstructure testing, X-Ray Diffraction, Differential Scanning Calorimetry and Shape Memory Effect. From the results of a review paper the heat treatment process affects the microstructure that exists in the shape memory alloy, so that it also affects the shape memory effect produced. In Cu-based alloys, solution treatment and aging are the heat treatments that most affect changes in microstructure and shape memory effect, because solution treatments affect the formation of the martensite (β’) phase and aging influences the formation of the α phase. In Ni-Ti alloys the aging and annealing heat treatment influences the phase change if it is carried out above 400 ° C.
