Recovery of ductility observed in liquid gallium induced embrittlement of polycrystalline silver
Polycrystalline silver is embrittled by liquid gallium immediately after intimate contact between the solid and the liquid metals is made.When the tensile test is performed at room temperature,recovery of ductility has been observed if the contact time is long enough.This recovery is induced by formation of an intermetallic compound between silver and gallium.When the specimen is stressed above 420 K,embrittlement is not observed even if the contact time between the solid and liquid metals is short.This is the ductility trough reported in various solid and liquid metal couples that cause the liquid metal embrittlement.Although loss of embrittlement occurs as a function of contact time and as a function of test temperature,it may be difficult to connect the ductility trough with contact time dependent recovery from embrittlement,and there seems two independent recovery processes.
