• Some Consideration on the Low Temperature Brittleness of Iron Crystals

抄録

The plastic behaviour of iron crystals fractured at low temperature have been observed using X-ray as an aid of consideration about "Transition Temperature".<BR>Iron single crystals were made by strain-recrystallization method and Laue photographs were taken before and after the crystals were fractured at low temperature from -180°C to room temperature.<BR>The macroscopic morphology of fractured part of the specimen are shear type and shrink locally, and the direction of incident X-ray beam for Laue photogruphs were normal and parallel to the edge of sheared plane.<BR>The Laue photographs from one shows obvious Central streeks following Debye ring from (110). The latter produces severely deformed spots which have fine structures and Debye ring as well as former. The Debye ring have assymmetlic intense accumulation.<BR>The Laue photographs taken from another direction show strange and fine streaks as photo. IV (a)-(c).<BR>We report here the Consideration from these characteristic Laue photographs.
