Microstructurally-Induced Embrittlement of Archaeological Silver

Abstract

Microstructurally-induced embrittlement of archaeological silver is character by grain boundary fracture. This is most likely due to impurity elements segregating to grain boundaries and reducing their cohesive strength. Empirical and theoretical concepts of segregation-induced embrittlement are considered with respect to silver and the impurity elements in archaeological silver, furthermore considering the special nature of grain boundaries and the influence of grain size. The report ends with surveys of diagnostic techniques and possible remedial measures for embrittled archaeological silver.
