β¦ Synopsis
The labyrinth (or two-dimensional wall) structure has been found in single crystals fatigued &axially at zero mean stress. This structure had been observed previously in poIycrystals but it was thought possibte that it rest&d from interactions between n~~~u~ng grains.
R&sum&-Nous avons trouvk la structure en labyrinthe (ou i paroi bidimensionn~lle~ dans des monocristaux soumis a une fatigue uniaxialc de contrainte moyenne nulle. Cette structure avait deja iti observ6e dans des polycristaux, mais on per&t qu'elle pouvait rCsulter d'interactions entre grains voisins.
Zusammenfassung-Die
Labyrinth-oder zweidimensionale Wandstruktur wurde in Einkristallen heohachtet, die einachsig hei einer mittleren Spannung von Null ermtidet warden waren. Diese Struktur ist unprGnglich in Polykristallen gefunden worden, wodurch angenommen wurde. dag sie miiglicherweise aus der Wechselwirkung zwischen henachbarten Kiirnern herriihrt.

An experimentally based investigation is presented of the dislocation structure and of glide effects occurring in single slip oriented nickel crystals cyclically deformed at 77 K until saturation of the stress amplitude. Special attention is paid to a comparison of slip and structure phenomena obser
