... and is a strengthener in alpha titanium alloys (unalloyed titanium), but too much oxygen causes embrittlement of the alpha phase. The presence of an alpha case in an alpha-beta titanium alloy, such as Ti-6Al-4V, can cause a reduction in the mechanical properties of the material [ 1 ]. The potential absorption of oxygen...

... temperatures in 6351-T6 aluminum alloy, which contains small amounts of lead (>10 ppm). It is perhaps unclear whether these failures should be classified as SMIE or grain-boundary segregation. The lead is contained in the alloy and apparently diffuses to grain boundaries near stress concentrations, where...

... commercial metals and alloys are classically intergranular. Near the final fracture area, the grain facets are usually smooth and the grain edges sharply defined. As the source of the embrittler is approached, the fracture takes on a rounded appearance, because there is a layer of embrittler metal...
