Institution National Aerospace Laboratory NLR Date 2001-08-14 Abstract Archaeological silver may be embrittled by long-term corrosion and microstructural changes. The embrittlement increases with increasing grain size, and the combination of a large grain size with synergistic embrittlement (conjoint action of corrosion-induced and microstructurally-induced embrittlement) is particularly detrimental. Micromechanical models of cracking that incorporate the grain size provide insight into the severity of embrittlement. Severely embrittled artifacts are frangible or even friable To reference this document use: http://resolver.tudelft.nl/uuid:b85e565d-9cdb-4ee1-baee-b785eca6def3 Publisher Nationaal Lucht- en Ruimtevaartlaboratorium Access restriction Campus only Source NLR Technical Publication TP 2001-369 Part of collection Aerospace Engineering Reports Document type report Rights (c)2001 National Aerospace Laboratory NLR Files PDF 2001-369.pdf 7.28 MB Close viewer /islandora/object/uuid:b85e565d-9cdb-4ee1-baee-b785eca6def3/datastream/OBJ/view
