Special Issue Information

Dear Colleagues,

Shape memory alloys, a type of intelligent material that exhibits a unique shape memory effect and superelasticity, demonstrate significant application potential in fields such as aerospace, biomedical engineering, and mechanical engineering.

The present special subject is primarily focused on multidimensional research encompassing theory, experimentation, computation, and simulation of shape memory alloys. Theoretically, it examines the phase transformation mechanisms and constitutive relationships in shape-memory alloys. Experimentally, it aims to develop new types of shape memory alloys and their related microstructures, as well as their martensitic transformations and mechanical and functional properties. Simulation and calculation utilize advanced algorithms to unveil the correlations between microstructures and macroscopic properties.

We sincerely invite scholars from home and abroad in the fields of martensitic transformation and shape memory alloys to share their latest research findings, thereby propelling shape memory alloys from fundamental research towards broader and more in-depth applications and injecting new vitality into the development of this field.

Abstract
In this paper, the interfacial bonding properties between (110)NiTi and (200)TiN interfaces, as well as the adsorption capacity of Cl on the surfaces of (110)NiTi and (200)TiN, were investigated using the first-principles computational method based on density [...] Read more.
In this paper, the interfacial bonding properties between (110)NiTi and (200)TiN interfaces, as well as the adsorption capacity of Cl on the surfaces of (110)NiTi and (200)TiN, were investigated using the first-principles computational method based on density functional theory (DFT). Four types of interfacial models between (110)NiTi and (200)TiN were developed. It was found that the interfacial bonding energies of the four interface models are greater than zero, indicating stable interface bonding between (110)NiTi and (200)TiN. For comparison, model III (N of (200)TiN is located at the bridge size between Ti and Ni in (110)NiTi) has the largest Wad value of 9.773 J/m2, which is attributed to stronger N-Ti bonding at the interface. Based on interface model III, an interfacial model of Cl at three different adsorption locations (top, bridge, and hole) on the (110)NiTi and (200)TiN surfaces, respectively, was constructed. The results reveal that the adsorption energies of Cl on the surface of (110)NiTi are significantly less than those of the Cl on the surface of (200)TiN. This suggests that (110)NiTi is more likely to react with Cl. Hence, the introduction of a TiN layer on the surface of NiTi alloy can effectively improve its corrosion resistance. Full article
