报告摘要:
Cellular and architected materials are referred to as mechanical metamaterials whenapplied in structural, load-bearing, or similar funetions. By regulating porosity andstrategically arranging materials, employing them only in necessary areas, metamaterialsare not only lighter than their fully solid equivalents but can also be engineered to achievespecific mechanical properties. Particularly, the structure and porosity of metamaterialscan also be controlled to tailor thermal, acoustic, or electromagnetic properties. Thedevelopment of various Additive Manufacturing (AM) techniques has greatly advancedthe study of metamaterials. Furthermore, the development of laser powder bed fusion(LPBF) technique allows the fabrication of geometries that are challenging or costly to betabricated with conventional manufacturing technologies. In this study, we developed bio.inspired or metamaterials, and investigated their multifunctional properties, includingcompressive behavior, thermal characteristics, vibration attenuation, and sound absorptionThe performance mechanisms and their trade-offs were carefully explained using varioustypes of structures such as truss lattice, foam, and triply periodic minimal surface TPMS).

报告摘要:
The development of high-strength metals is vital for achieving resourceconservation and high energy efficiency, but avoiding a reduction in theirductility remains a challenge. In this study, an innovative combination of grainboundary engineering and heterogeneous structures is proposed to significantlyenhance the strength-ductility synergy of metals using laser powder bed fusion(LPBF) technique, and novel super austenitic stainless steel (SASS) matrixcomposites with significantly enhanced strength-ductility synergy aredemonstrated
