Thermal Expansion of Several Technical Metals from -255° to 300°C
The thermal-expansion measurement system used Is shown In Fig. 1. This system consists of suitable cryogenic dewars, vacuum equipment, an Interferometer-dllatometerj automatic temperature control system, temperature-measurement equipment and a hoist for assembly of the dilatometer and specimen. The dewars, Interferometer, and dilatometer are supported on a stable platform to reduce effects of mechanical vibrations.
