...Abstract Abstract Equipment in which an assembly of in-line cylindrical components rotated in water at 1040 rpm displayed excessive vibration after less than one hour of operation. The malfunction was traced to an aluminum alloy 6061-T6 combustion chamber that was part of the rotating assembly...

... 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...

... with respect to each other but also crystallographic differences. For example, 7000-series aluminum alloys are susceptible to SCC when solution treated and aged (T6 condition), yet the same alloy can be safely used when solution treated and overaged (T7 condition) ( Ref 8 , 9 ). (An aluminum alloy with a T6...
