Abstract

Results of 77 Kelvin creep tests on OFHC copper specimens have been obtained and are shown to support previously published results presented by researchers at the National Institute of Standards and Technology (NIST). The reproduction of the copper results obtained by NIST using the Texas A&M system provides credibility to both systems. This is particularly important when the lack of commercial cryogenic creep systems results in individualized measurement techniques and the degree of measurement difficulty is high. A suggested standard for the simplified comparison of materials which exhibit “exhaustive” creep behavior is also given.
