“…γ 1 1 phase means that thick plate martensite, β 1 1 is sign of thin plate martensite. The particle size analysis was obtained with the Debye Scherrer equation based on the XRD graph and its graph was drawn (Figure 3) [17,18]. The particle size of chromium decreased with heat treatment.…”

Shape memory alloys are known for their ability to return to their original shape under the influence of external factors (temperature, magnetic field and mechanical stress). Although NiTi-based alloys come to mind first when the shape memory effect is mentioned, CuAl-based alloys are very popular alternatives. The low cost of copper-based alloys is the biggest reason to study. In this study, the heat treatment effects of Cu-Al-X (X: Cr, Ti) (% weight) on some thermodynamic parameters, crystal structure and microstructure of shape memory alloy were investigated at three different temperatures (973 K, 1073 K and 1173 K). The changes in the thermal transformation of the samples were determined by DSC (Differential Scanning Calorimetry) and the changes in the crystal structure were determined by X-ray diffraction (XRD), Scanning Electron Microscope (SEM) and optical microscope device. According to DSC measurement, the temperature hysteresis of the samples decreased after the heat treatment. Besides, as the entropy change decreased, the thermal stability of the samples increased. It can be seen that the particle size of the CuAlCr alloy decreased with increasing temperature. The particle size of the CuAlTi alloy increased with increasing temperature. SEM and optical images showed that chromium (Cr) was more dissolved in the alloy compared to titanium (Ti) into CuAl alloy.

“…Cu-based SMAs have three binary alloys : (Cu-Sn, Cu-Zn, and Cu-Al) as they are shown in Table 1 of Cu-based SMAs in Figure 5 [30,31]. To change and enhance the good properties of binary SMAs one or more extra additive elements are added to produce ternary and quaternary SMAs.…”

One of the best types of smart materials is Shape Memory Alloys (SMAs), which have more applications in modern technology such as aerospace, automotive, biomedical, civil engineering, robotics, and so on. Among all parts of them NiTi-based, and Cu–based are more focused on because they have some interesting properties that have made them more widely used in modern technology. In this work, the classifications and applications of SMAs according to the different application fields like biomedical, automotive, and aerospace have been reviewed. Besides the characteristic of (NiTi-based, Cu – based) and the comparison between them in many areas such as: In terms of cost, creation, corrosion resistivity, density, and electrical and thermal conductivity were represented. Each of NiTi and Cu-based SMAs has many useful applications and strengths, but they have some limitations.

“…[2][3][4] In addition, magnetic metallic materials make substantial contributions to diverse domains, including rail transport (electric motors in automobiles [5] ), aerospace (permanent magnet machines [6] ), medicine (magnetic resonance imaging (MRI) scanners [7] ), and beyond. [8][9][10][11][12][13][14] Nevertheless, magnetic metallic materials frequently experience temperature variations in these aforementioned applications. This becomes particularly critical when the material reaches its critical temperature, as the magnetic metallic material will then cease to function effectively.…”

In this study, based on the Force-Heat Equivalence Energy Density Principle, a theoretical model for magnetic metallic materials is developed which characterizes the temperature-dependent magnetic anisotropy energy by considering the equivalent relationship between magnetic anisotropy energy and heat energy, and then the relationship between the magnetic anisotropy constant and saturation magnetization is considered. Finally, we formulate a temperature-dependent model for saturation magnetization, revealing the inherent relationship between temperature and saturation magnetization. Our model predicts the saturation magnetization for nine different magnetic metallic materials at different temperatures, exhibiting satisfactory agreement with experimental data. Additionally, the experimental data used as reference points are at or near room temperature. Compared to other phenomenological theoretical models, this model is considerably more accessible than the data required at 0 K. The index included in our model is set to a constant value which is equal to 10/3 for materials other than Fe, Co, and Ni. For transition metals (Fe, Co, and Ni in this paper), the index is 6 in the range of 0 K to 0.65T cr (critical temperature), and 3 in the range of 0.65T cr to T cr, unlike other models where the adjustable parameters vary according to each material. In addition, our model provides a new way for designing and evaluating magnetic metallic materials with superior magnetic properties over a wide range of temperatures.
