Role of Grain Size and Recrystallization Texture in the Corrosion Behavior of Pure Iron in Acidic Medium

This work investigates the role of grain size and recrystallization texture in the corrosion behavior of pure iron in 0.1 M sulfuric acid solution. Annealing heat treatment was applied to obtain samples with different average grain sizes (26, 53 and 87 µm). Optical microscopy, X-ray diffraction and electron backscatter diffraction techniques...

The role of grain size in embrittlement of archaeological silver

Archaeological silver may be embrittled by long-term corrosion and microstructural changes. The embrittlement of artifacts increases with increasing grain size. This is explained by considering the grain boundary character and models describing the interactions between microcracks, lattice dislocations and grain boundaries. Severely embrittled...
