Più complesso della semplice cricca da corrosione, l'infragilimento da metallo liquido (LME) è un fenomeno per cui alcuni metalli duttili diventano fragili se esposti a specifici metalli liquidi, provocando un cedimento improvviso e catastrofico sotto sforzo. Questo fenomeno si verifica attraverso la rapida penetrazione del metallo liquido lungo i confini dei grani del metallo solido, indebolendo così i legami interatomici e facilitando l'innesco e la propagazione delle cricche. L'LME dipende fortemente dalla combinazione di metalli solidi e liquidi coinvolti, nonché da fattori quali la temperatura e le sollecitazioni applicate. Esempi industriali comuni sono l'infragilimento dell'acciaio da parte dello zinco liquido o dell'alluminio durante i processi di zincatura a caldo.

Assembly of flexible interconnects using sedimentation
Patent published on the 2025-03-06 in WO under Ref WO2025048947 by VIRGINIA TECH INTELLECTUAL PROPERTIES INC [US] (Bartlett Michael D [us], Ho Dong Hae [us])
Abstract: Embodiments of interplanar interconnects, intraplanar interconnects, and methods for forming the same in rigid, flexible, and stretchable substrates are described. In one example, a method for forming interplanar interconnects in a substrate includes injecting a solution into a mold cavity of a molding structure. The solution includes a polymer matrix and liquid metal elements. The method further includes performing a curing process on the solution to form an interplanar interconnect in the poly[...]
