โœฆ Synopsis


An apparatus is described which enables a specimen of liquid mercury to be introduced into a specially shaped mould at room temperature, solidified by cooling to 77 K, cold worked by surface hammering, recrystallized by anneafing at 160 K, and then strained in tension at temperatures down to 20 K. The x-ray diffraction pattern of the specimen can be recorded at any desired stage in this series of operations. The apparatus can also be used for the study of low temperature tensile or compression deformation in materials which are fine-grained polycrystalline solids at room temperature.
