Dynamic stress corrosion cracking in silicon crystal

Liquid metal embrittlement of molybdenum by the eutectic gallium-indium-tin alloy

“…As the tested molybdenum (99.9% purity) normally fails in a brittle mode from the room temperature up to 200 °C with a high crack speed, the liquid metal adsorption has a null or a small effect on the already brittle fracture process. It therefore seems difficult, at least in our notched geometry, to assess concurrent fracture processes (between the intrinsic brittle fracture and the adsorption induced fracture for example unlike what was achieved on brittle silicon with the adsorption of dioxygen via the gas phase [28] ). Testing quantitatively a Griffith type cleavage fracture mechanism where liquid metal adsorption induces a surface energy reduction is unfortunately not possible in this geometry with such a high DBTT material.…”
