Abstract
Shape Memory Alloy (SMA) adalah pengembangan dari smart materials yang dapat memulihkan bentuk ke bentuk yang ditentukan setelah mengalami deformasi. Berdasarkan komposisi, terdapat berbagai macam jenis SMA salah satunya Cu-Based. Cu-based shape memory alloy memiliki kelebihan dari sisi harga yang lebih murah dan prosedur fabrikasi yang sederhana. Pada penelitian ini, paduan yang digunakan adalah Cu-12,36-Al-2,06Mn dengan perlakuan panas yang diberikan yaitu homogenizing, solution treatment. Terdapat dua variasi media pendingin yang digunakan yaitu brine dan air. Selain itu, terdapat variasi holding time pada proses solution treatment yaitu 5 menit, 10 menit, dan 15 menit. Pengujian yang dilakukan untuk menganalisis pengaruh variabel diatas adalah pengujian Optical Emission Spectroscopy (OES), pengujian X-Ray Diffraction (XRD), pengujian metalografi, pengujian Differential Scanning Calorimetry (DSC), pengujian kekerasan, dan pengujian shape memory effect. Didapatkan hasil bahwa semakin lamanya holidng time solution treatment, maka presentase fasa twinned martensite yang terbentuk semakin banyak. Fasa twinned martensite tertinggi pada spesimen BR15 dengan metode solution treatment selama 15 menit dengan media pendingin brine sebesar 49,93. Didapatkan pula semakin lama proses solution treatment maka semakin lunak. Kekerasan tertinggi terdapat pada BR5 dengan metode solution treatment selama 5 menit dengan media pendingin air sebesar 256,8±1,83 HV. Nilai recovery shape memory effect meningkat seiring lamanya holding time soltion treatment. Presentase recovery shape memory effect tertinggi didapatkan pada spesimen BR15 sebesar 70%.

Shape Memory Alloy (SMA) is a development of smart materials that can recover shape to a specified form after deformation. Based on composition, there are various types of SMA, one of which is Cu-Based. Cu-based shape memory alloy has advantages in terms of lower price and simple fabrication procedures. In this study, the alloy used was Cu12.36-Al-2.06Mn with heat treatment given, namely homogenizing, solution treatment. There are two variations of cooling media used, namely brine and water. In addition, there are holding time variations in the solution treatment process, namely 5 minutes, 10 minutes, and 15 minutes. Tests conducted to analyze the effect of the above variables are Optical Emission Spectroscopy (OES) testing, X-Ray Diffraction (XRD) testing, metallographic testing, Differential Scanning Calorimetry (DSC) testing, hardness testing, and shape memory effect testing. It was found that the longer the holding time solution treatment, the more the percentage of twinned martensite phase formed. The highest twinned martensite phase in specimen BR15 with the solution treatment method for 15 minutes with brine cooling media amounted to 49.93. It was also found that the longer the solution treatment process, the softer. The highest hardness was found in BR5 with the solution treatment method for 5 minutes with water cooling media at 256,8±1,83 HV. The recovery shape memory effect value increases with the length of the holding time of the solution treatment. The highest percentage of recovery shape memory effect was obtained in BR15 specimen by 70%.
