Special Issue Information

Dear Colleagues,

The unique properties of shape memory alloys make them highly valuable in various industries, as they can undergo phase transformations and recover their original shape in response to external stimuli. This ability makes them ideal for use in products that require deformation or mechanical actuation. In recent years, advancements have been made in developing new types of shape memory alloys and exploring their functional properties. The goal is to design and develop alloys that are more efficient and better suited to meet the demands of various industries, such as aerospace, automotive, electronic, and biomedical. The Special Issue of Materials aims to bring together the latest research and developments in this field and provide insights into the multifunctional properties and applications of shape memory alloys. The issue covers topics such as new functionalities, high-throughput multiscale materials computing and machine learning for efficient design methods, additive manufacturing for innovative synthesis and processing, and advanced material characterization techniques.

We invite submissions of manuscripts to this Special Issue that address the listed topics.

Porous Ni-Ti shape memory alloys (SMAs) have been widely studied in biomedical and engineering applications. Porous Ni-Ti SMAs were obtained via self-propagating high-temperature synthesis (SHS), and their microstructure, phase transformation, and mechanical properties were investigated. This article presents the results of a study of changes in the microstructure, phase transformation, and mechanical properties of porous Ni-Ti SMAs when Ni and Ti metal powders were preliminarily subjected to ultrasonic activation at various periods. It was determined that the porosity of the obtained alloy samples was 62–68 vol%. The microstructure was composed of the main matrix Ni-Ti phase and the accompanying Ti and Ti2-Ni phases. The results show that the hardness 34.1–86.8 HB and elastic modulus 4.2–10.8 GPa increased with an increase in the ultrasonic activation time of the samples. The phase transformation temperature of the Ni-Ti shape memory alloy remained almost unchanged under the influence of ultrasonic treatment. Full article
