Special Issue Information

Dear Colleagues,

Advanced materials with various functionalities or structural features have been increasingly utilized in recent years to meet the sophisticated demands of modern technology. These materials encompass soft materials, functionally graded materials, quasicrystals, and smart materials and structures. Thermal failure presents a significant concern for many advanced materials and structures across diverse thermal environments. Examples include space exploration devices operating in extreme temperatures, high-energy laser manufacturing of microelectronic devices, combustion chambers in jet engines, overheating of electronic devices during service cycles, and thermal fatigue of solar panels, among others. Gaining a deeper understanding of thermal failure mechanisms is crucial for designing reliable advanced materials and structures.

This Special Issue is dedicated to exploring the thermal reliability of advanced materials and structures under various thermal disturbances. Topics range from transient heating in ultrafast laser fabrication to the quenching of advanced metal alloys, thermal cycles in electronic devices, and transient heat conduction in heterogeneous microstructures. We welcome papers that address heat conduction, thermal stress analysis, thermal fatigue and fracture of advanced materials and structures, and related subjects. By showcasing recent advancements in this critical area, we aim to enhance our understanding of the thermal reliability of advanced materials and structures.

Taking austenitic stainless-steel bellows as the research object, a finite element model for the heat treatment of austenitic stainless-steel bellows was constructed based on ABAQUS CAE 2022. The physical properties of the bellows after the heat treatment were analyzed using experimental and simulated curve processing analysis methods. The changes in residual stress and deformation in relation to the bellows under different cooling times were explored, as well as the distribution of residual stress and deformation at a certain cooling time. The results show that as the cooling time of the heat treatment increases, the residual stress of the bellow decreases significantly, the reduction rate accelerates, and the degree of deformation gradually decreases. When the cooling time of the heat treatment is 900 s, the residual stress of the wave peak in the middle position of the bellow is relatively small, and the residual stress value of the wave valley along the axis direction does not change significantly. The deformation degree of the wave peak and valley axis direction is relatively uniform. Full article
