✦ Synopsis

Abstracts torsion testing under cyclic loading to lo6 cycles. It was learned that carbon-carbon creeps or takes on a permanent deformation, but is resistant to fatigue loading and in general can retain its stiffness and strength up to lo6 cycles. Fiber bundle slipping and re-sticking is believed to be the mechanism by which creep takes place and the higher the composite density the less pronounced the effect.

## Abstract Austenitic stainless steels are materials commonly used in cryotechnology. At extremely low temperatures these steels still exhibit good mechanical properties along with sufficient ductility. However high mechanical loads combined with low temperatures may induce martensitic transfomati
