Abstract
Perkembangan teknologi di bidang industri otomotif akan terus menghasilkan inovasi, salah satunya shape memory alloy actuator yang berfungsi sebagai penggerak sistem dalam kendaraan bermotor. Shape memory alloy merupakan material yang mempunyai kemampuan untuk kembali ke bentuk semula jika dikenai deformasi dan dipanaskan di atas temperatur transformasi, dikenal sebagai sifat shape memory effect (SME). Penelitian ini membahas mengenai pengaruh variasi temperatur, media quenching solution treatment dan proses artificial aging pada paduan Cu-14,6Zn-7,41Al terhadap struktur mikro, kekerasan, dan SME. Hasil dari penelitian ini, didapatkan pengaruh kenaikan temperatur solution treatment mengakibatkan ukuran butir lebih besar pada struktur mikro. Media quenching glycol mengakibatkan butir yang terbentuk lebih seragam dibanding spesimen dengan media quenching ice water. SME tertinggi didapatkan oleh spesimen dengan solution treatment temperatur 850 ℃ dengan media pendingin glycol, dengan nilai shape recovery 100%. Proses artificial aging menyebabkan kenaikan pada nilai kekerasan, dengan nilai tertinggi 346 ± 1,63 VHN dan penurunan SME, dengan nilai shape recovery 10%.

Technology development in automotive industry will continue to produce innovations, one of which is shape memory alloy actuator that works as a driving system in vehicles. Shape memory alloy is material that has ability to transform back to its initial shape when affected by deformation and heated above the transformation temperature, which known as shape memory effect (SME). This study will discuss influence of temperature, solution treatment media variations and artificial aging process in Cu-14,6Zn-7,41Al shape memory alloy for microstructure, hardness and shape memory effect. The results of this study, obtained influence of increasing the solution treatment temperature resulting larger grain size in the microstructure. Glycol quenching media resulted in more uniform grains formed than specimens with ice water quenching media. The highest SME was obtained by specimen with solution treatment temperature of 850 ℃ by glycol quenching media, with value of 100 % shape recovery. The artificial aging process causes increase in the hardness value, with the highest value of 346 ± 1.63 VHN and decrease in SME, with a shape recovery value of 10%.
