Abstract

Paduan Shape Memory Alloy (SMA’s) sudah dikembangkan selama dua puluh lima tahun terakhir, saat ini paduan alloy berbasis Cu banyak digunakan sebagai alternatif paduan Ni-Ti karena memiliki biaya yang lebih ekonomis. Paduan Cu-Zn-Al memiliki sifat shape memory effext pada rentan komposisi tertentu yaitu 60%-80% Cu, 15%-30% Zn , dan 3%-10% Al dalam berbagai perbandingan. Dalam pembuatan material shape memory alloy diperlukan beberapa proses perlakuan panas antara lain homogenizing, annealing, solution treatment dan terakhir dilakukan artificial aging. Kemudian dilakukan beberapa pengujian yaitu pengujian metalografi, XRD, XRF, DSC, dan SME. Dalam review paper ini dilakukan penambahan unsur untuk mengetahui pengaruh shape memory effect dan struktur mikro paduan. Dari hasil review paper didapatkan adanya penambahan unsur mengakitabatkan perubahanya sturktur mikro dimana pada unsur terjadi pengecilan grain size yang paling optimal pada unsur Gd, unsur Fe dan unsur Ti mengalami pembesaran grain size. Adanya penambahan unsur juga mempengaruhi SME dimana unsur Gd memiliki nilai paling tinggi yaitu 98,6% , pada unsur Fe dan unsur Ti mengalami penurunan nilai SME ============================================================ Shape Memory Alloy (SMA) alloys have been developed over the past twenty-five years, currently Cu-based alloys are widely used as an alternative to Ni-Ti alloys because they have a more economical cost. Alloys of Cu-Zn-Al have effext shape memory properties in certain susceptible compositions namely 60% -80% Cu, 15% -30% Zn, and 3% -10% Al in various comparisons. In making shape memory alloy material, several heat treatment processes are needed, including homogenizing, annealing, solution treatment and finally artificial aging. Then a number of tests were conducted, namely metallographic, XRD, XRF, DSC, and SME testing. In this paper review the addition of elements was carried out to determine the effect of shape memory effect and microstructure of the alloy. From the results of a review paper, it was found that there was an addition of elements due to changes in the microstructure, where the element had the most optimal grain size reduction in the Gd element, the Fe element and Ti the element had an enlarged grain size. The addition of elements also affects the SME where Gd elements have the highest value that is 98.6%, the Fe element and the Ti element decreases the SME value
