Special Issue Information

Dear Colleagues,

Shape memory alloys (SMAs) possess unique functional properties, including the shape memory effect and superelasticity, via their essential thermoelastic martensitic transformation, enabling them to restore their shape after large deformations. In addition to their functional properties, for example, near-equiatomic NiTi alloys also exhibit excellent mechanical properties, high wear resistance, good biocompatibility, and high corrosion resistance, making them widely used in aerospace, automotive, and medical applications. However, due to the common poor machinability and weldability of shape memory alloys, their practical applications are usually limited to simple geometric structures, such as sheets, wires, tubes, and so on. The fabrication problems seriously impede and restrict their application and development. Therefore, it is necessary and meaningful to explore new fabrication technologies and application scenarios for shape memory alloys to promote further development.

In this Special Issue, we welcome reviews and research articles in the areas of fabrication and application of shape memory alloys. Topics of interest include, but are not limited to, the following:

  • Coatings of shape memory alloys;
  • Surface treatment of shape memory alloys;
  • Additive manufacturing of shape memory alloys;
  • Solid-state refrigeration of shape memory alloys;
  • Fabrication technologies of shape memory alloys;
  • Novel functional properties of shape memory alloys;
  • Simulation and calculation of shape memory alloys;
  • Electron microscopy of shape memory alloys;
  • Novel applications of shape memory alloys.

Abstract
The effects of slag components on the sulfur distribution ratio {(wt.%S)/[wt.%S]} were analyzed using thermodynamic calculations. On this basis, the effects of the slag with different binary basicities (wt.% CaO/wt.% SiO2 = 3.0, 5.0, 7.0, 9.0 and 11.0) and Al2O [...] Read more.
The effects of slag components on the sulfur distribution ratio {(wt.%S)/[wt.%S]} were analyzed using thermodynamic calculations. On this basis, the effects of the slag with different binary basicities (wt.% CaO/wt.% SiO2 = 3.0, 5.0, 7.0, 9.0 and 11.0) and Al2O3 contents (wt.% Al2O3 = 12, 16, 20 and 24) on the desulfurization behavior were investigated. The results show that the binary basicity and Al2O3 content were the main factors that affected the desulfurization. And an increase in the binary basicity and a decrease in the content of Al2O3, increase the sulfide capacity of the slag. In the early stage of the smelting process, the desulfurization process was limited due to the high content of oxides, such as FeO and MnO in the slag, and the sulfur content in the alloy melt reached 35 ppm. After the final deoxidation of the Si-Ca alloy, the desulfurization rate was significantly increased, and the maximum desulfurization rate reached 44.12%. During the ladle standing, the sulfur content in the alloy melt changed little because of the limitation of kinetics. The rate-limiting step of the desulfurization process was the diffusion of sulfur in the alloy melt. Full article
