Abstract
Abstract The deformation of Cu single crystals at 4.2 K was studied by simultaneous measurements of mechanical and electrical properties. The aim was to extend the study of low-temperature deformation to higher strains than are usually employed; thus most of the crystals were stretched to failure. The deformation can be divided into three distinct regions. In region A (which includes stages I and II of plastic deformation) the crystal deforms by slip. In region B there is twinning but no slip; at the end of region B the specimen is 70% twinned. The crystal enters region C as a fine layer structure consisting of twin and parent lamellae; in this region there is no more twinning and deformation proceeds by slip. Examination of the deformation-induced resistivity and resistivity annealing confirms the conclusion that flow stress in region A is due to dislocation accumulation and indicates that in region C other obstacles, such as twin-parent interfaces, are also important. The annealing data, together with other evidence, suggest that elimination of short vacancy dipoles and loops by pipe diffusion accounts for the recoverable component of the resistivity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
