“…From this stereographic projection, it is expected that etch pits are only formed within (001) cones having about 36 ° half angle. This value is in agreement with a value of 35 ° reported previously from observations of etch pits formed on various fiat faces of tungsten by Wolff (1958) and Berlec (1962). To confirm these results, a [001] hemispherically shaped single crystal was prepared.…”

The formation of etch pits directly on the mantle surface of cylindrical single crystals rather than on flat surfaces, as it is usually performed, allows easier and more accurate determination of the crystal orientation. The application of this technique to tungsten single crystals subjected to compression tests at low temperature allows an easy identification of the twinning systems. This technique is well adapted to single crystals subjected to mechanical tests mainly because it does not require the preparation of flat surfaces before or after the test to reveal etch pits. Producing flat surfaces could induce stress within the crystals that in turn could activate slip or twinning mechanisms and would, therefore, give wrong results.
