Research Progress on Structural Regulation and Mechanical Behavior of Dealloyed Porous Copper

Abstract:

Dealloyed porous copper exhibits exceptional and adaptable functional properties, offering broad application potential in thermal management, catalytic sensing, and shock absorption. Structural regulation represents a key approach for enhancing its functional properties, whereas mechanical behavior is essential to ensure structural integrity and reliability under service conditions. Based on recent advances in structural regulation and mechanical properties of dealloyed porous copper, this review summarized the dealloying mechanisms and structural features of diverse precursor systems, including intermetallic compounds, solid solutions, and immiscible alloys, and also outlined the corresponding strategies for pore structural regulation. Moreover, it reviewed the current research progress on mechanical behavior of porous copper, and highlighted its major strengthening approaches and predictive models. Finally, this review outlined the key research directions of structural design and mechanical properties for the future.
