At present, SMAs have been applied to the engineering fields of machinery, energy, control, medicine and defense etc. The growing number of certificated patents and commercial products indicates SMAs are highly potential advance materials. However, the trend of industrial products, especially 3C product, is toward the miniaturization. In the mean time, most of SMAs applications in MEMS and medical fields are also in miniature product. The SMAs used in miniature products demand good properties performance, and therefore, the properties improvement of SMAs becomes an important issue at present. The purpose of this 3-year integral project is aimed to improve the properties of SMAs, included TiNi-based SMAs, magnetoelastic Fe-Pd-X SMAs. Fe-Mn-Si-Ni-(Cr) SMAs and porous TiNi SMAs. From the integration of experience and experiment, we can more understand and improve the SMAs’ properties. Therefore, a 3-year term integrated project is proposed. Prof. S.K. Wu of National Taiwan University (NTU) is the principle investigator of this integrated project. There are four subprojects. The first one is focused on the improvement of TiNi-based SMAs properties and is investigated by Prof. S.K. Wu. The second one studies the improvement of magnetoelastic Fe-Pd-X SMAs properties. This subproject is guided by Prof. C.T. Hu of National Tsing- Hua University. The third one is focused on the SME/PE improvement of Fe-based SMAs and is conducted by Prof. H.C. Lin of NTU. The fourth one is focused on the improvement of porous TiNi SMAs properties. This subproject is investigated by Prof. K.S. Hwang of NTU. Obviously, the goal of this integrated project is aimed to study intensively the properties improvement of SMAs from the above-mentioned research group. These researches will approach from the viewpoints of both experiment and experience. Through the mutual cooperation of these experts and their experience in the research, the goal of this integrated project can be reached with confidence.形狀記憶合金性能之改進實驗及經驗之整合整合型總計畫Shape memory AlloysProperties ImprovementExperiment and Experience,改進形狀記憶合金性能之研究-總計畫
