Abstract

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.
