Type of article: Article

Summary

LITERATURE REVIEW OF THE NUMEROUS HEAT TRANSFER STUDIES OF THE SUPERCONDUCTING NIOBIUM-BASED MATERIALS, ESPECIALLY AT LIQUID HELIUM TEMPERATURES. ON THE OPPOSITE, FEW STUDIES OF THE THERMOPHYSICAL PROPERTIES OF THE RARE EARTH-BASED MATERIALS HAVE BEEN CONDUCTED, SO THAT THEIR STRUCTURE AND MECHANICAL CHARACTERISTICS ARE NOT WELL UNDERSTOOD. THE AUTHORS HAVE DEVELOPED AN EXPERIMENTAL INVESTIGATION OF THE THERMAL CONDUCTIVITY OF YTTRIUM-AND BISMUTH-BASED MATERIALS, OVER A TEMPERATURE RANGE OF 120 TO 290 K AND 320 TO 360 K, RESPECTIVELY. THE THERMAL CONDUCTIVITIES OF THE TWO MATERIALS ALMOST DO NOT DEPEND ON TEMPERATURE OVER THE RANGE TESTED. THE SUPERCONDUCTING MATERIAL FABRICATION METHODHAS A SIGNIFICANT EFFECT ON THE OVERALL THERMAL PROPERTIES OF EACH MATERIAL.
