Abstract:

The fifth semi-annual technical reports are collected from three subcontractors of an ARPA-sponsored program to study the very low-temperature properties of structural materials in support of the development of superconducting machinery. The program is outlined and new research results are reported. Low-temperature results are given for the following properties elastic, tensile, fatigue and fracture, thermal expansion, specific heat, thermal and magnetothermal conductivity, electrical and magnetic. Effects of processing and fabrication are also considered for some properties weld and braze-joint properties are included. Tensile and compressive properties at 4 K of selected composite materials are presented. Author
