Abstract
  • The thesis was an investigation into the mechanism of precipitation from solid solution in an Aluminum-0.7% Magnesium-0.6% Silicon alloy containing iron impurities. Laue x-ray diffraction patterns were obtained from solution heat treated and aged single crystal specimens in various crystallographic orientations. Precipitation related streaking was detected on some of the patterns from aged specimens. From an analysis of the streaking it was concluded that precipitate stringlets formed during the early stages of precipitation and that the stringlets were coherent with the solid solution in the <100> directions. From the experimental results it was not possible to determine the degree of strengthening due to coherency.
