Abstract

Shape Memory Alloy (SMA) adalah sebuah paduan logam yang memiliki sifat memori pada bentuknya saat dipanaskan di atas temperatur tertentu. Paduan Shape Memory memiliki salah satu sifat dari Shape Memory Effect atau superelastis. Untuk membentuk Shape memory Alloy dapat dilakukan melalui proses perlakuan panas berupa Solution Treatment pada media pendingin (Quenchant) tertentu. Dimana akan terbentuk fasa twinned martensit yang terdeformasi menjadi detwinned martensit, serta akan kembali ke bentuk semula setelah dipanaskan atau pembebanan dihilangkann. Artificial Aging yang diberikan pada Shape Memory Alloy akan mempengaruhi struktur mikro dan sifat mekaniknya. Pengujian yang dilakukan pada penelitian ini berupa Optical Emission Spectrometry (OES), X-Ray Difraction (XRD), Metalografi, dan Kekerasan. Komposisi paduan Cu-11,9Zn-6,72Al terdapat 3 fasa utama setelah pengujian XRD, fasa α, β, γ. Paduan tersebut membentuk twinned martensite yang secara visual dapat diliat dari hasil pengujian metalografi sehingga dapat dijadikan menjadi bahan shape memory alloy. Untuk nilai kekerasan tertinggi pada spesimen IW850T200 237 ± 3,741657 HV.
===============================================================
Shape Memory Alloy (SMA) is a metal alloy that has memory properties in its shape and can recover its shape when heated above a certain temperature.alloys Shape Memory have either the nature of the Shape Memory Effect or are superelastic. To form a Shape memory Alloy, it can be done through a heat treatment process in the form of Solution Treatment oncooling media (Quenchant). Where aphase will be formed twinned martensite which into deforms detwinned martensite, and will return to its original shape after heating or loading is removed. Artificial Aging given to Shape Memory Alloy will affect its microstructure and mechanical properties. Tests carried out in this study are Optical Emission Spectrometry (OES), X-Ray Difraction (XRD), Metallography, and Hardness. The composition of the Cu-11,9Zn-6,72Al alloy produces 3 main phases after going through XRD testing, the α, β, γ phases. The alloy forms twinned martensite which can be visually seen through metallographic test results so that it can be used as amaterial shape memory alloy. For the highest hardness value on the IW850T200 specimen 237 ± 3,741657 HV.
