Plates 3 to 6] The contrast associated with dislocations in deformed a-iron has been examined under a large number of two-beam diffracting conditions using transmission electron microscopy. Dis locations are shown to go effectively out of contrast for several different diffracting vectors (g), and the angular relations between these vectors are often such that the observed absence of contrast cannot always be associated with the condition g. b = 0, where b is the Burgers vector of thedoi:10.1098/rspa.1968.0176 fatcat:zo7424wx4rfnjdekwpfmrdmb3a
