Summary: Elastocaloric cooling is a potentially more efficient and environmentally friendly refrigeration technique compared to conventional methods. However, the main challenge lies in the lifetime of the devices, which can be improved by activating them through compression and optimizing the flow system. This study shows promising results in achieving a maximum temperature span and cooling power with a high cycle endurance under compressive cycling.

Summary: Multicomponent high-entropy Cantor alloys, discovered in the late 1970s, occupy a vast region of multi-component phase space and exhibit excellent mechanical properties due to high configurational entropy. The complexity of local atomic configurations and associated lattice strains in these alloys contributes to their unique characteristics and potential for further enhancement and optimization.

Summary: The study explored the crystal structure, martensitic transformation behavior, magnetic properties, and magnetic-field-induced reverse martensitic transformation of Co64V15(Si21-xAlx) alloys. It was observed that with increasing Al composition, the microstructure changes from martensitic to parent phase, with crystal structures determined as D0(22) and L2(1) respectively. Additionally, both the ferromagnetic state of the parent phase and martensite phase were witnessed, with martensitic transformation temperatures decreasing and Curie temperatures increasing with higher Al contents.

Summary: This study tracked the disordering process of structural voids in Ni-Mn alloy samples, revealing an increase in thermal vacancy concentration at high temperatures, and showing that excess vacancy concentrations large enough to increase low-temperature macroscopic magnetization can be retained by quenching. The research also demonstrated the significant impact of the thermal history on material properties such as ordering temperatures in these systems.

Summary: The study evaluated the solvus temperature of the FCC phase in Fe-34Mn-xAl-4Cr-7.5Ni shape memory alloys with varying Al content, as well as their abnormal grain growth and superelasticity at different temperatures. The results showed that increasing Al content led to a decrease in solvus temperature of the FCC phase, finer FCC precipitates, and easier formation of large grains. The newly developed Fe-34Mn-14Al-4Cr-7.5Ni alloy exhibited superelasticity over a wide temperature range with minimal temperature-dependence of critical stress.

Summary: In this paper, a new Pd2MnGa Heusler-type MMSMA with an extremely small dissipation energy and hysteresis is reported. The microstructures, crystal structures, magnetic properties, martensitic transformations, and magnetic-field-induced strain of aged Pd2MnGa alloys are investigated. The low values of dissipation energy and hysteresis make the Pd2MnGa alloy a promising candidate for high-efficiency MMSMAs.

Summary: Phase transformations were studied in Ti501xNi47+xFe3 (x = 0.0-1.0) alloys. The B2/R transformation temperature and entropy change decreased gradually with increasing x, but significantly declined with the appearance of the I phase at around x = 0.40. The existence of the R phase at low temperatures was confirmed by in situ XRD measurements. However, the microstructure of the R phase was different for x = 0.40 compared to x = 0.00 and 0.35, indicating a significant influence of the I phase on the microstructure and phase stability of the R phase.
