| Summary: | In this modern era, many types of alloys have been developed by researchers to facilitate human work. One of them is an alloy that can remember its shapes or commonly known as Shape Memory Alloys (SMAs). Where the use of this type of alloy is very large, such as in the fields of aerospace, automotive, industrial equipment, robotics, biomedical engineering, to the fields of textiles and fashion. This is because SMAs alloys have shape memory, superelastic, corrosion-resistant, and biocompatible properties. Many articles have discussed the effect of alloying on the characteristics of binary NiTi shape memory alloy, but there has been no systematic review of the application of these alloys.
In this literature review, a search was carried out through two databases, Science Direct and CORE, using keywords related to the research problem, "Ni-Ti-X" AND "Shape Memory Alloy" AND "Characteristics" AND "Application" where X = Al, V, Cr, Fe, Co, Cu, Zr, Nb, Pd, Hf, and Pt with a time limit for publishing articles in the last 10 years (2010-2020). Then the results of the study (n = 372) were selected using the PRISMA method by selecting duplicate articles (n-139), then selected the title and abstract of the article (n-135), and then all the contents of the full text were selected (n-78) so that 20 final articles were obtained which will be discussed in this review, 55 articles outside the selection process are used as supporting and complementary articles.
Based on the literature review results, it was concluded that the effect of alloying in binary NiTi alloys (SMAs) can have a whole different effect on the characteristics of the alloys. Such as increasing or decreasing the transformation temperature, widening or narrowing thermal hysteresis, as well as increasing corrosion resistance and alloy biocompatibility. In addition, the addition of the alloying element can change the method of the binary NiTi alloy manufacturing process, because the alloying element can cause unwanted impurities. In this review, it was also found that the addition of an alloying element to the binary NiTi alloys also had an effect on its application in various fields. Several alloys provide properties suitable for application in the aerospace, automotive, robotics, and biomedical fields depending on which elements they provide. |
