The electron microscopic observation of mechanical twins in indium

    Research outputpeer-review


    Mechanical twinning in indium has been observed by using an electron microscope. The twinning elements are determined by selected — area diffraction; they are
    K1 = (101) η1 = [101]
    K2 = (101] η2 = [101].
    No evidence is found for a pole mechanism for twinning; the observations suggest that on the contrary the Bell-Cahn mechanism is operative. A brief comment is made on the origin of contrast at coherent twin-interfaces. It is found that the contrast at lattice defects is considerably improved by cooling the specimen.
