Abstract

The evolution of temperature and thermal stresses during friction stir welding of AI6061-T6 was investigated by means of in situ, time resolved neutron diffraction technique. A method was developed to deconvolute the temperature and stress from the lattice spacing changes measured by neutron diffraction. The deep penetration capability of neutrons made it possible for the first time to obtain the temperature and thermal stresses inside a friction stir weld. © 2007 Institute of Materials, Minerals and Mining.
