TLDR
In a review paper of this nature it is impossible to cover all aspects of such a large subject as the mechanical properties of materials at low temperatures, and any choice of topics must inevitably leave some areas completely uncovered and others barely indicated as mentioned in this paper.Abstract:
I N a review paper of this nature it is impossible to cover adequately all aspects of such a large subject as the mechanical properties of materials at low temperatures, and any choice of topics must inevitably leave some areas completely uncovered and others barely indicated. The selection of topics has been made on personal preference but it is hoped that this paper will convey some idea of the present position in the major branches of this subject.read more

TL;DR: Using in situ neutron diffraction, this work demonstrates the interaction of a rich variety of deformation mechanisms in high-entropy alloys at 15 K, which began with dislocation slip, followed by stacking faults and twinning, before transitioning to inhomogeneous deformation by serrations.

Plastic deformation of nickel single crystals at low temperatures
TL;DR: In this article, the work-hardening parameters obtained are discussed in terms of dislocation theory that has been developed mainly on the basis of data on Al and Cu, and the advantages of the temperature change method for an investigation of the flow stress are pointed out following a theoretical analysis of the relation between this method and that of the work hardening parameters.

Low‐Temperature Deformation of Copper Single Crystals
TL;DR: In this article, the effects of reactor irradiations on discontinuous slip and on twinning were also studied and it was determined that the occurrence of twinning was unaffected by the irradiations.
