Abstract
Shape Memory Alloys (SMA) merupakan paduan logam yang dapat mengingat bentuknya semula walaupun telah mengalami deformasi. Untuk kembali ke bentuk asalnya, Shape Memory Alloys harus dipanaskan sampai dengan temperatur tertentu. Terdapat berbagai macam Shape Memory Alloys dengan paduan yang berbeda-beda serta komposisi yang berbeda pula. Pada penelitian ini, Shape Memory Alloys yang digunakan adalah Cu-12,1Al-1,89Mn. Paduan tersebut diberi serangkaian perlakuan panas agar Shape Memory Effect dapat terbentuk. Perlakuan panas yang diberikan adalah homogenizing, annealing, serta solution treatment. Terdapat tiga variasi waktu annealing yang diberikan, yaitu selama 3 jam, 5 jam, dan 7 jam. Kemudian, terdapat variasi pada metode solution treatment, yaitu step quench dan up quench. Paduan yang telah diberi perlakuan panas tersebut kemudian dianalisis dengan melakukan beberapa pengujian. Pengujian yang dilakukan adalah Optical Emission Spectroscopy (OES), pengujian X-Ray Diffraction (XRD), pengujian metalografi, pengujian kekerasan, pengujian Differential Scanning Calorimetry (DSC), serta pengujian Shape Memory Effect (SME). Hasil yang didapatkan dari beberapa pengujian tersebut adalah, ukuran fasa twinned martensite semakin besar seiring dengan meningkatnya waktu annealing. Hal tersebut berpengaruh kepada nilai kekerasan yang dimiliki oleh paduan, dimana semakin besar ukuran fasa, maka kekerasan yang dimiliki oleh paduan semakin menurun. Akan tetapi, ukuran fasa twinned martensite juga berpengaruh kepada Shape Memory Effect, dimana semakin besar ukuran fasa, maka nilai Shape Memory Effect yang dimiliki oleh paduan semakin baik. Pada penelitian ini, spesimen SQA07 (Annealing 7 jam dan metode solution treatment step quench) memiliki nilai kekerasan sebesar 206 HV, dan sifat Shape Memory Effect terbaik, yaitu dengan persentase shape recovery sebesar 60%.

Shape Memory Alloys (SMA) are metal alloys that can remember their original shape even though they have been deformed. To return to its original shape, Shape Memory Alloys must be heated to a certain temperature. There are various Shape Memory Alloys with different alloys and different compositions. In this study, the Shape Memory Alloys used were Cu-12,1Al-1,89Mn. The alloy is given a series of heat treatments so that the Shape Memory Effect can be formed. The heat treatment given is homogenizing, annealing, and solution treatment. There are three variations of annealing time given, namely for 3 hours, 5 hours, and 7 hours. Then there are variations on the solution treatment method, namely step quench and up quench. The alloy that has been given heat treatment will then be analyzed by carrying out several tests. The tests carried out were Optical Emission Spectroscopy (OES), X-Ray Diffraction (XRD) testing, metallographic testing, hardness testing, Differential Scanning Calorimetry (DSC) testing, and Shape Memory Effect (SME) testing. The results obtained from these tests are that the size of the twinned martensite phase increases as the annealing time increases. This affects the hardness value of the alloy, where the larger the phase size, the lower the hardness of the alloy. However, the size of the twinned martensite phase also affects the Shape Memory Effect, where the larger the phase size, the better the Shape Memory Effect value of the alloy will be. In this study, the SQA07 specimen (7 hour annealing and solution treatment step quench method) had a hardness value of 206 HV, and the best Shape Memory Effect property, with a shape recovery proportion of 60%.
