Desublimation of flowing vapor with a thermal resistance between the coolant and the heat sink surface

Results are shown of a study concerning the desublimation of water vapor flowing between parallel plates, with a finite coefficient of heat transfer between coolant and heat sink surface.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 24, No. 3, pp. 419–424, March, 1973.     

An apparatus for measuring internal friction of films during the process of plastic deformation in the temperature range from 4.2 to 300 K

An apparatus is described in which internal friction (Q^?1) can be measured for specimens of dimensions 0.01 × 2 × 15 mm³ during the process of plastic deformation in the temperature range from 4.2 to 300 K and the frequency range 10² to 10⁴ Hz. The cryostat has three independent helium spaces, allowing Q^?1 to be measured in the magnetic field of a superconducting solenoid. The relative error in measuring Q^?1 during plastic deformation is ?5% at a deformation rate of 10^?3.
