Venkataswamy, MA and Sujata, M and Madan, M and Suresh Kumar, M and Bhaumik, SK (2006) Analysis of raw material used for the fabrication of front and rear stub wing spars. Project Report. National Aerospace Laboratories, Bangalore.Full text not available from this repository.
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.
