Abstract

A series of international, interlaboratory comparisons of tensile and fracture-toughness tests for prestandardization and refining of these test procedures at liquid-helium temperature using the same materials has been coordinated under the Versailles Project on Advanced Materials and Standards (VAMAS). High-strength stainless steels, YUS170 and SUS316LN, and a titanium alloy were used for this program. Future plans include testing an aluminum alloy and a composite material. Tensile and fracture-toughness properties were much less scattered under the limited testing conditions that were used in this program.
