Tensile testing of materials, such as mercury, that freeze at low temperature usually requires casting of the material in a mold, transferring the cast specimen onto precooled test fixtures through a moisture-free environment, followed by cooling to the desired test temperatures and then testing. The device shown in the figure accomplishes the entire procedure in a single cycle comprising room temperature assembly, cooling to the desired cryogenic temperatures, and testing at those temperatures.
