Full text not available from this repository.Abstract
Microstructural study suggests that the raw material billet used for the fabrication of stub wing spars did not receive adequate hot working. The microstructure was found to have a thick network of second phase at the grain boundaries. Also, the microstructure resembles more of a cast structure than a wrought product. The pit-like indications observed during fluorescent dye penetrant test is believed to be due to falling off of the second phase from the material during machining and/or inferior corrosion resistance due to a highly inhomogeneous microstructure.
